Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012188, here are decompositions:

  • 5 + 1012183 = 1012188
  • 17 + 1012171 = 1012188
  • 29 + 1012159 = 1012188
  • 41 + 1012147 = 1012188
  • 101 + 1012087 = 1012188
  • 109 + 1012079 = 1012188
  • 139 + 1012049 = 1012188
  • 157 + 1012031 = 1012188

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 1, 2188 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 2188-10-01 (MMDYYYY (US, single-digit day))
  • 2188-01-10 (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 1,012,188 and was likely granted around 1911.

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