Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018372, here are decompositions:

  • 59 + 1018313 = 1018372
  • 71 + 1018301 = 1018372
  • 101 + 1018271 = 1018372
  • 149 + 1018223 = 1018372
  • 263 + 1018109 = 1018372
  • 281 + 1018091 = 1018372
  • 353 + 1018019 = 1018372
  • 419 + 1017953 = 1018372

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 1, 8372 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 8372-10-01 (MMDYYYY (US, single-digit day))
  • 8372-01-10 (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 1,018,372 and was likely granted around 1911.

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