Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140672, here are decompositions:

  • 13 + 140659 = 140672
  • 43 + 140629 = 140672
  • 61 + 140611 = 140672
  • 79 + 140593 = 140672
  • 139 + 140533 = 140672
  • 151 + 140521 = 140672
  • 199 + 140473 = 140672
  • 223 + 140449 = 140672

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 140,672 and was likely granted around 1872.

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