Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018436, here are decompositions:

  • 7 + 1018429 = 1018436
  • 79 + 1018357 = 1018436
  • 127 + 1018309 = 1018436
  • 229 + 1018207 = 1018436
  • 313 + 1018123 = 1018436
  • 379 + 1018057 = 1018436
  • 439 + 1017997 = 1018436
  • 547 + 1017889 = 1018436

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 1, 8436 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 8436-10-01 (MMDYYYY (US, single-digit day))
  • 8436-01-10 (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 1,018,436 and was likely granted around 1911.

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