Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100290, here are decompositions:

  • 11 + 100279 = 100290
  • 19 + 100271 = 100290
  • 23 + 100267 = 100290
  • 53 + 100237 = 100290
  • 83 + 100207 = 100290
  • 97 + 100193 = 100290
  • 101 + 100189 = 100290
  • 107 + 100183 = 100290

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 100,290 and was likely granted around 1870.

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