Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115328, here are decompositions:

  • 7 + 115321 = 115328
  • 19 + 115309 = 115328
  • 79 + 115249 = 115328
  • 127 + 115201 = 115328
  • 211 + 115117 = 115328
  • 229 + 115099 = 115328
  • 271 + 115057 = 115328
  • 307 + 115021 = 115328

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 115,328 and was likely granted around 1871.

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