Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145960, here are decompositions:

  • 11 + 145949 = 145960
  • 29 + 145931 = 145960
  • 131 + 145829 = 145960
  • 137 + 145823 = 145960
  • 239 + 145721 = 145960
  • 251 + 145709 = 145960
  • 257 + 145703 = 145960
  • 281 + 145679 = 145960

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 145,960 and was likely granted around 1873.

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