Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108100, here are decompositions:

  • 11 + 108089 = 108100
  • 59 + 108041 = 108100
  • 89 + 108011 = 108100
  • 101 + 107999 = 108100
  • 149 + 107951 = 108100
  • 173 + 107927 = 108100
  • 197 + 107903 = 108100
  • 227 + 107873 = 108100

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 108,100 and was likely granted around 1870.

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