Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012490, here are decompositions:

  • 43 + 1012447 = 1012490
  • 67 + 1012423 = 1012490
  • 79 + 1012411 = 1012490
  • 211 + 1012279 = 1012490
  • 223 + 1012267 = 1012490
  • 229 + 1012261 = 1012490
  • 277 + 1012213 = 1012490
  • 307 + 1012183 = 1012490

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 1, 2490 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 2490-10-01 (MMDYYYY (US, single-digit day))
  • 2490-01-10 (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 1,012,490 and was likely granted around 1911.

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