Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145936, here are decompositions:

  • 3 + 145933 = 145936
  • 5 + 145931 = 145936
  • 107 + 145829 = 145936
  • 113 + 145823 = 145936
  • 137 + 145799 = 145936
  • 179 + 145757 = 145936
  • 227 + 145709 = 145936
  • 233 + 145703 = 145936

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 145,936 and was likely granted around 1873.

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