Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102258, here are decompositions:

  • 5 + 102253 = 102258
  • 7 + 102251 = 102258
  • 17 + 102241 = 102258
  • 29 + 102229 = 102258
  • 41 + 102217 = 102258
  • 59 + 102199 = 102258
  • 61 + 102197 = 102258
  • 67 + 102191 = 102258

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 102,258 and was likely granted around 1870.

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