Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030072, here are decompositions:

  • 3 + 1030069 = 1030072
  • 5 + 1030067 = 1030072
  • 11 + 1030061 = 1030072
  • 23 + 1030049 = 1030072
  • 41 + 1030031 = 1030072
  • 53 + 1030019 = 1030072
  • 83 + 1029989 = 1030072
  • 89 + 1029983 = 1030072

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 3, 0072 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0072-03-01 (DMMYYYY (Euro, single-digit day))
  • 0072-10-03 (MMDYYYY (US, single-digit day))
  • 0072-03-10 (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 1,030,072 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 1030072 first appears in π at position 487,395 of the decimal expansion (the 487,395ordinal-suffix:th 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.
