Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100790, here are decompositions:

  • 3 + 100787 = 100790
  • 43 + 100747 = 100790
  • 97 + 100693 = 100790
  • 181 + 100609 = 100790
  • 199 + 100591 = 100790
  • 241 + 100549 = 100790
  • 271 + 100519 = 100790
  • 307 + 100483 = 100790

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 100,790 and was likely granted around 1870.

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