Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156790, here are decompositions:

  • 41 + 156749 = 156790
  • 71 + 156719 = 156790
  • 83 + 156707 = 156790
  • 107 + 156683 = 156790
  • 113 + 156677 = 156790
  • 131 + 156659 = 156790
  • 149 + 156641 = 156790
  • 167 + 156623 = 156790

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 156,790 and was likely granted around 1873.

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