Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538000, here are decompositions:

  • 59 + 537941 = 538000
  • 101 + 537899 = 538000
  • 227 + 537773 = 538000
  • 251 + 537749 = 538000
  • 257 + 537743 = 538000
  • 389 + 537611 = 538000
  • 401 + 537599 = 538000
  • 431 + 537569 = 538000

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 538,000 and was likely granted around 1894.

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