Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126490, here are decompositions:

  • 3 + 126487 = 126490
  • 17 + 126473 = 126490
  • 29 + 126461 = 126490
  • 47 + 126443 = 126490
  • 131 + 126359 = 126490
  • 149 + 126341 = 126490
  • 167 + 126323 = 126490
  • 173 + 126317 = 126490

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 126,490 and was likely granted around 1872.

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