Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100644, here are decompositions:

  • 23 + 100621 = 100644
  • 31 + 100613 = 100644
  • 53 + 100591 = 100644
  • 97 + 100547 = 100644
  • 107 + 100537 = 100644
  • 127 + 100517 = 100644
  • 151 + 100493 = 100644
  • 197 + 100447 = 100644

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 100,644 and was likely granted around 1870.

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