Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031278, here are decompositions:

  • 11 + 1031267 = 1031278
  • 47 + 1031231 = 1031278
  • 89 + 1031189 = 1031278
  • 137 + 1031141 = 1031278
  • 197 + 1031081 = 1031278
  • 359 + 1030919 = 1031278
  • 389 + 1030889 = 1031278
  • 431 + 1030847 = 1031278

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 3, 1278 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1278-03-01 (DMMYYYY (Euro, single-digit day))
  • 1278-10-03 (MMDYYYY (US, single-digit day))
  • 1278-03-10 (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 1,031,278 and was likely granted around 1912.

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