Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031540, here are decompositions:

  • 7 + 1031533 = 1031540
  • 19 + 1031521 = 1031540
  • 61 + 1031479 = 1031540
  • 79 + 1031461 = 1031540
  • 109 + 1031431 = 1031540
  • 127 + 1031413 = 1031540
  • 193 + 1031347 = 1031540
  • 241 + 1031299 = 1031540

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 3, 1540 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1540-03-01 (DMMYYYY (Euro, single-digit day))
  • 1540-10-03 (MMDYYYY (US, single-digit day))
  • 1540-03-10 (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 1,031,540 and was likely granted around 1912.

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