Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538398, here are decompositions:

  • 31 + 538367 = 538398
  • 41 + 538357 = 538398
  • 67 + 538331 = 538398
  • 89 + 538309 = 538398
  • 97 + 538301 = 538398
  • 101 + 538297 = 538398
  • 131 + 538267 = 538398
  • 139 + 538259 = 538398

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 538,398 and was likely granted around 1894.

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