Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156700, here are decompositions:

  • 17 + 156683 = 156700
  • 23 + 156677 = 156700
  • 29 + 156671 = 156700
  • 41 + 156659 = 156700
  • 59 + 156641 = 156700
  • 107 + 156593 = 156700
  • 179 + 156521 = 156700
  • 233 + 156467 = 156700

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 156,700 and was likely granted around 1873.

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