Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149312, here are decompositions:

  • 3 + 149309 = 149312
  • 43 + 149269 = 149312
  • 61 + 149251 = 149312
  • 73 + 149239 = 149312
  • 139 + 149173 = 149312
  • 151 + 149161 = 149312
  • 193 + 149119 = 149312
  • 199 + 149113 = 149312

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 149,312 and was likely granted around 1873.

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