Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528638, here are decompositions:

  • 7 + 528631 = 528638
  • 79 + 528559 = 528638
  • 127 + 528511 = 528638
  • 151 + 528487 = 528638
  • 349 + 528289 = 528638
  • 421 + 528217 = 528638
  • 541 + 528097 = 528638
  • 547 + 528091 = 528638

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 528,638 and was likely granted around 1894.

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