Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018470, here are decompositions:

  • 23 + 1018447 = 1018470
  • 31 + 1018439 = 1018470
  • 41 + 1018429 = 1018470
  • 59 + 1018411 = 1018470
  • 113 + 1018357 = 1018470
  • 157 + 1018313 = 1018470
  • 179 + 1018291 = 1018470
  • 199 + 1018271 = 1018470

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 1, 8470 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 8470-10-01 (MMDYYYY (US, single-digit day))
  • 8470-01-10 (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 1,018,470 and was likely granted around 1911.

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