Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521374, here are decompositions:

  • 5 + 521369 = 521374
  • 11 + 521363 = 521374
  • 17 + 521357 = 521374
  • 107 + 521267 = 521374
  • 131 + 521243 = 521374
  • 173 + 521201 = 521374
  • 197 + 521177 = 521374
  • 311 + 521063 = 521374

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 521,374 and was likely granted around 1894.

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