Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122798, here are decompositions:

  • 37 + 122761 = 122798
  • 79 + 122719 = 122798
  • 97 + 122701 = 122798
  • 199 + 122599 = 122798
  • 241 + 122557 = 122798
  • 271 + 122527 = 122798
  • 349 + 122449 = 122798
  • 397 + 122401 = 122798

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 122,798 and was likely granted around 1871.

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