Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100490, here are decompositions:

  • 7 + 100483 = 100490
  • 31 + 100459 = 100490
  • 43 + 100447 = 100490
  • 73 + 100417 = 100490
  • 79 + 100411 = 100490
  • 97 + 100393 = 100490
  • 127 + 100363 = 100490
  • 157 + 100333 = 100490

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 100,490 and was likely granted around 1870.

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