Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172382, here are decompositions:

  • 31 + 172351 = 172382
  • 61 + 172321 = 172382
  • 103 + 172279 = 172382
  • 139 + 172243 = 172382
  • 163 + 172219 = 172382
  • 211 + 172171 = 172382
  • 229 + 172153 = 172382
  • 313 + 172069 = 172382

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 172,382 and was likely granted around 1874.

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