Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125618, here are decompositions:

  • 67 + 125551 = 125618
  • 79 + 125539 = 125618
  • 109 + 125509 = 125618
  • 211 + 125407 = 125618
  • 307 + 125311 = 125618
  • 331 + 125287 = 125618
  • 349 + 125269 = 125618
  • 397 + 125221 = 125618

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 125,618 and was likely granted around 1871.

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