Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171430, here are decompositions:

  • 3 + 171427 = 171430
  • 29 + 171401 = 171430
  • 47 + 171383 = 171430
  • 89 + 171341 = 171430
  • 101 + 171329 = 171430
  • 113 + 171317 = 171430
  • 131 + 171299 = 171430
  • 137 + 171293 = 171430

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 171,430 and was likely granted around 1874.

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