Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139174, here are decompositions:

  • 5 + 139169 = 139174
  • 41 + 139133 = 139174
  • 53 + 139121 = 139174
  • 83 + 139091 = 139174
  • 107 + 139067 = 139174
  • 197 + 138977 = 139174
  • 251 + 138923 = 139174
  • 257 + 138917 = 139174

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 139,174 and was likely granted around 1872.

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