Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101040, here are decompositions:

  • 13 + 101027 = 101040
  • 19 + 101021 = 101040
  • 31 + 101009 = 101040
  • 41 + 100999 = 101040
  • 53 + 100987 = 101040
  • 59 + 100981 = 101040
  • 83 + 100957 = 101040
  • 97 + 100943 = 101040

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 101,040 and was likely granted around 1870.

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