Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018850, here are decompositions:

  • 37 + 1018813 = 1018850
  • 43 + 1018807 = 1018850
  • 61 + 1018789 = 1018850
  • 73 + 1018777 = 1018850
  • 139 + 1018711 = 1018850
  • 181 + 1018669 = 1018850
  • 199 + 1018651 = 1018850
  • 229 + 1018621 = 1018850

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 1, 8850 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 8850-10-01 (MMDYYYY (US, single-digit day))
  • 8850-01-10 (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 1,018,850 and was likely granted around 1911.

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