Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101390, here are decompositions:

  • 7 + 101383 = 101390
  • 13 + 101377 = 101390
  • 31 + 101359 = 101390
  • 43 + 101347 = 101390
  • 67 + 101323 = 101390
  • 97 + 101293 = 101390
  • 103 + 101287 = 101390
  • 109 + 101281 = 101390

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 101,390 and was likely granted around 1870.

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