Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940840, here are decompositions:

  • 11 + 940829 = 940840
  • 23 + 940817 = 940840
  • 53 + 940787 = 940840
  • 59 + 940781 = 940840
  • 101 + 940739 = 940840
  • 107 + 940733 = 940840
  • 113 + 940727 = 940840
  • 137 + 940703 = 940840

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 940,840 and was likely granted around 1909.

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