Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115166, here are decompositions:

  • 3 + 115163 = 115166
  • 13 + 115153 = 115166
  • 43 + 115123 = 115166
  • 67 + 115099 = 115166
  • 109 + 115057 = 115166
  • 193 + 114973 = 115166
  • 199 + 114967 = 115166
  • 277 + 114889 = 115166

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 115,166 and was likely granted around 1871.

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