Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000440, here are decompositions:

  • 11 + 1000429 = 1000440
  • 13 + 1000427 = 1000440
  • 17 + 1000423 = 1000440
  • 31 + 1000409 = 1000440
  • 37 + 1000403 = 1000440
  • 43 + 1000397 = 1000440
  • 47 + 1000393 = 1000440
  • 59 + 1000381 = 1000440

Showing the first eight; more decompositions exist.

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 1,000,440 and was likely granted around 1911.

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