Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145956, here are decompositions:

  • 7 + 145949 = 145956
  • 23 + 145933 = 145956
  • 53 + 145903 = 145956
  • 59 + 145897 = 145956
  • 127 + 145829 = 145956
  • 137 + 145819 = 145956
  • 149 + 145807 = 145956
  • 157 + 145799 = 145956

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 145,956 and was likely granted around 1873.

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