Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101538, here are decompositions:

  • 5 + 101533 = 101538
  • 7 + 101531 = 101538
  • 11 + 101527 = 101538
  • 37 + 101501 = 101538
  • 61 + 101477 = 101538
  • 71 + 101467 = 101538
  • 89 + 101449 = 101538
  • 109 + 101429 = 101538

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 101,538 and was likely granted around 1870.

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