Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180612, here are decompositions:

  • 43 + 180569 = 180612
  • 71 + 180541 = 180612
  • 73 + 180539 = 180612
  • 79 + 180533 = 180612
  • 101 + 180511 = 180612
  • 109 + 180503 = 180612
  • 139 + 180473 = 180612
  • 149 + 180463 = 180612

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 180,612 and was likely granted around 1875.

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