Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115228, here are decompositions:

  • 5 + 115223 = 115228
  • 17 + 115211 = 115228
  • 101 + 115127 = 115228
  • 149 + 115079 = 115228
  • 167 + 115061 = 115228
  • 227 + 115001 = 115228
  • 401 + 114827 = 115228
  • 419 + 114809 = 115228

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 115,228 and was likely granted around 1871.

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