Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126558, here are decompositions:

  • 7 + 126551 = 126558
  • 11 + 126547 = 126558
  • 17 + 126541 = 126558
  • 41 + 126517 = 126558
  • 59 + 126499 = 126558
  • 67 + 126491 = 126558
  • 71 + 126487 = 126558
  • 97 + 126461 = 126558

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 126,558 and was likely granted around 1872.

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