Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172048, here are decompositions:

  • 17 + 172031 = 172048
  • 47 + 172001 = 172048
  • 101 + 171947 = 172048
  • 131 + 171917 = 172048
  • 167 + 171881 = 172048
  • 179 + 171869 = 172048
  • 197 + 171851 = 172048
  • 389 + 171659 = 172048

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 172,048 and was likely granted around 1874.

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