Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038990, here are decompositions:

  • 37 + 1038953 = 1038990
  • 53 + 1038937 = 1038990
  • 109 + 1038881 = 1038990
  • 157 + 1038833 = 1038990
  • 163 + 1038827 = 1038990
  • 167 + 1038823 = 1038990
  • 179 + 1038811 = 1038990
  • 193 + 1038797 = 1038990

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 3, 8990 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 8990-03-01 (DMMYYYY (Euro, single-digit day))
  • 8990-10-03 (MMDYYYY (US, single-digit day))
  • 8990-03-10 (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 1,038,990 and was likely granted around 1912.

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