Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102672, here are decompositions:

  • 5 + 102667 = 102672
  • 19 + 102653 = 102672
  • 29 + 102643 = 102672
  • 61 + 102611 = 102672
  • 79 + 102593 = 102672
  • 109 + 102563 = 102672
  • 113 + 102559 = 102672
  • 139 + 102533 = 102672

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 102,672 and was likely granted around 1870.

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