Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140778, here are decompositions:

  • 5 + 140773 = 140778
  • 17 + 140761 = 140778
  • 19 + 140759 = 140778
  • 37 + 140741 = 140778
  • 47 + 140731 = 140778
  • 61 + 140717 = 140778
  • 89 + 140689 = 140778
  • 97 + 140681 = 140778

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 140,778 and was likely granted around 1872.

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