Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523942, here are decompositions:

  • 5 + 523937 = 523942
  • 113 + 523829 = 523942
  • 149 + 523793 = 523942
  • 179 + 523763 = 523942
  • 269 + 523673 = 523942
  • 311 + 523631 = 523942
  • 389 + 523553 = 523942
  • 401 + 523541 = 523942

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 523,942 and was likely granted around 1894.

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