Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521312, here are decompositions:

  • 3 + 521309 = 521312
  • 13 + 521299 = 521312
  • 31 + 521281 = 521312
  • 61 + 521251 = 521312
  • 139 + 521173 = 521312
  • 151 + 521161 = 521312
  • 193 + 521119 = 521312
  • 271 + 521041 = 521312

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 521,312 and was likely granted around 1894.

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