Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495242, here are decompositions:

  • 31 + 495211 = 495242
  • 43 + 495199 = 495242
  • 61 + 495181 = 495242
  • 103 + 495139 = 495242
  • 109 + 495133 = 495242
  • 199 + 495043 = 495242
  • 283 + 494959 = 495242
  • 439 + 494803 = 495242

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 495,242 and was likely granted around 1893.

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