Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101998, here are decompositions:

  • 11 + 101987 = 101998
  • 41 + 101957 = 101998
  • 59 + 101939 = 101998
  • 107 + 101891 = 101998
  • 191 + 101807 = 101998
  • 227 + 101771 = 101998
  • 251 + 101747 = 101998
  • 257 + 101741 = 101998

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 101,998 and was likely granted around 1870.

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