Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123908, here are decompositions:

  • 79 + 123829 = 123908
  • 151 + 123757 = 123908
  • 181 + 123727 = 123908
  • 241 + 123667 = 123908
  • 271 + 123637 = 123908
  • 277 + 123631 = 123908
  • 307 + 123601 = 123908
  • 409 + 123499 = 123908

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 123,908 and was likely granted around 1871.

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