Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101542, here are decompositions:

  • 5 + 101537 = 101542
  • 11 + 101531 = 101542
  • 29 + 101513 = 101542
  • 41 + 101501 = 101542
  • 53 + 101489 = 101542
  • 59 + 101483 = 101542
  • 113 + 101429 = 101542
  • 131 + 101411 = 101542

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 101,542 and was likely granted around 1870.

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