Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557538, here are decompositions:

  • 5 + 557533 = 557538
  • 17 + 557521 = 557538
  • 19 + 557519 = 557538
  • 89 + 557449 = 557538
  • 167 + 557371 = 557538
  • 199 + 557339 = 557538
  • 229 + 557309 = 557538
  • 257 + 557281 = 557538

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 557,538 and was likely granted around 1895.

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