Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180958, here are decompositions:

  • 179 + 180779 = 180958
  • 227 + 180731 = 180958
  • 257 + 180701 = 180958
  • 311 + 180647 = 180958
  • 389 + 180569 = 180958
  • 419 + 180539 = 180958
  • 461 + 180497 = 180958
  • 467 + 180491 = 180958

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 180,958 and was likely granted around 1875.

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