Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526420, here are decompositions:

  • 23 + 526397 = 526420
  • 29 + 526391 = 526420
  • 47 + 526373 = 526420
  • 53 + 526367 = 526420
  • 113 + 526307 = 526420
  • 131 + 526289 = 526420
  • 137 + 526283 = 526420
  • 149 + 526271 = 526420

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 526,420 and was likely granted around 1894.

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