Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125526, here are decompositions:

  • 17 + 125509 = 125526
  • 19 + 125507 = 125526
  • 29 + 125497 = 125526
  • 73 + 125453 = 125526
  • 97 + 125429 = 125526
  • 103 + 125423 = 125526
  • 127 + 125399 = 125526
  • 139 + 125387 = 125526

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 125,526 and was likely granted around 1871.

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