Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115130, here are decompositions:

  • 3 + 115127 = 115130
  • 7 + 115123 = 115130
  • 13 + 115117 = 115130
  • 31 + 115099 = 115130
  • 73 + 115057 = 115130
  • 109 + 115021 = 115130
  • 157 + 114973 = 115130
  • 163 + 114967 = 115130

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 115,130 and was likely granted around 1871.

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