Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145916, here are decompositions:

  • 13 + 145903 = 145916
  • 19 + 145897 = 145916
  • 37 + 145879 = 145916
  • 97 + 145819 = 145916
  • 109 + 145807 = 145916
  • 139 + 145777 = 145916
  • 157 + 145759 = 145916
  • 163 + 145753 = 145916

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 145,916 and was likely granted around 1873.

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