Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022986, here are decompositions:

  • 5 + 1022981 = 1022986
  • 23 + 1022963 = 1022986
  • 53 + 1022933 = 1022986
  • 137 + 1022849 = 1022986
  • 149 + 1022837 = 1022986
  • 257 + 1022729 = 1022986
  • 347 + 1022639 = 1022986
  • 353 + 1022633 = 1022986

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 2, 2986 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2986-02-01 (DMMYYYY (Euro, single-digit day))
  • 2986-10-02 (MMDYYYY (US, single-digit day))
  • 2986-02-10 (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 1,022,986 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 1022986 first appears in π at position 42,551 of the decimal expansion (the 42,551ordinal-suffix:st 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.
