Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042828, here are decompositions:

  • 29 + 1042799 = 1042828
  • 47 + 1042781 = 1042828
  • 197 + 1042631 = 1042828
  • 251 + 1042577 = 1042828
  • 257 + 1042571 = 1042828
  • 359 + 1042469 = 1042828
  • 389 + 1042439 = 1042828
  • 401 + 1042427 = 1042828

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 4, 2828 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2828-04-01 (DMMYYYY (Euro, single-digit day))
  • 2828-10-04 (MMDYYYY (US, single-digit day))
  • 2828-04-10 (DDMYYYY (Euro, single-digit month))
Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,042,828 and was likely granted around 1912.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1042828 first appears in π at position 44,773 of the decimal expansion (the 44,773ordinal-suffix:rd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
