Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012990, here are decompositions:

  • 23 + 1012967 = 1012990
  • 59 + 1012931 = 1012990
  • 71 + 1012919 = 1012990
  • 179 + 1012811 = 1012990
  • 227 + 1012763 = 1012990
  • 239 + 1012751 = 1012990
  • 257 + 1012733 = 1012990
  • 269 + 1012721 = 1012990

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 1, 2990 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 2990-10-01 (MMDYYYY (US, single-digit day))
  • 2990-01-10 (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 1,012,990 and was likely granted around 1911.

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