Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180670, here are decompositions:

  • 3 + 180667 = 180670
  • 23 + 180647 = 180670
  • 41 + 180629 = 180670
  • 47 + 180623 = 180670
  • 53 + 180617 = 180670
  • 101 + 180569 = 180670
  • 107 + 180563 = 180670
  • 131 + 180539 = 180670

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 180,670 and was likely granted around 1875.

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