Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188572, here are decompositions:

  • 53 + 188519 = 188572
  • 89 + 188483 = 188572
  • 113 + 188459 = 188572
  • 239 + 188333 = 188572
  • 269 + 188303 = 188572
  • 281 + 188291 = 188572
  • 311 + 188261 = 188572
  • 383 + 188189 = 188572

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 188,572 and was likely granted around 1875.

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