Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523666, here are decompositions:

  • 29 + 523637 = 523666
  • 89 + 523577 = 523666
  • 113 + 523553 = 523666
  • 173 + 523493 = 523666
  • 179 + 523487 = 523666
  • 233 + 523433 = 523666
  • 239 + 523427 = 523666
  • 263 + 523403 = 523666

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 523,666 and was likely granted around 1894.

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