Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123528, here are decompositions:

  • 11 + 123517 = 123528
  • 29 + 123499 = 123528
  • 37 + 123491 = 123528
  • 71 + 123457 = 123528
  • 79 + 123449 = 123528
  • 89 + 123439 = 123528
  • 101 + 123427 = 123528
  • 109 + 123419 = 123528

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 123,528 and was likely granted around 1871.

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