Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512138, here are decompositions:

  • 37 + 512101 = 512138
  • 79 + 512059 = 512138
  • 127 + 512011 = 512138
  • 199 + 511939 = 512138
  • 229 + 511909 = 512138
  • 241 + 511897 = 512138
  • 271 + 511867 = 512138
  • 307 + 511831 = 512138

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 512,138 and was likely granted around 1893.

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