Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139952, here are decompositions:

  • 13 + 139939 = 139952
  • 31 + 139921 = 139952
  • 61 + 139891 = 139952
  • 139 + 139813 = 139952
  • 151 + 139801 = 139952
  • 193 + 139759 = 139952
  • 199 + 139753 = 139952
  • 223 + 139729 = 139952

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 139,952 and was likely granted around 1872.

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