Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100788, here are decompositions:

  • 19 + 100769 = 100788
  • 41 + 100747 = 100788
  • 47 + 100741 = 100788
  • 89 + 100699 = 100788
  • 139 + 100649 = 100788
  • 167 + 100621 = 100788
  • 179 + 100609 = 100788
  • 197 + 100591 = 100788

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 100,788 and was likely granted around 1870.

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