Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100620, here are decompositions:

  • 7 + 100613 = 100620
  • 11 + 100609 = 100620
  • 29 + 100591 = 100620
  • 61 + 100559 = 100620
  • 71 + 100549 = 100620
  • 73 + 100547 = 100620
  • 83 + 100537 = 100620
  • 97 + 100523 = 100620

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 100,620 and was likely granted around 1870.

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