Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126976, here are decompositions:

  • 53 + 126923 = 126976
  • 137 + 126839 = 126976
  • 149 + 126827 = 126976
  • 233 + 126743 = 126976
  • 257 + 126719 = 126976
  • 263 + 126713 = 126976
  • 293 + 126683 = 126976
  • 503 + 126473 = 126976

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 126,976 and was likely granted around 1872.

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