Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101888, here are decompositions:

  • 19 + 101869 = 101888
  • 139 + 101749 = 101888
  • 151 + 101737 = 101888
  • 277 + 101611 = 101888
  • 307 + 101581 = 101888
  • 421 + 101467 = 101888
  • 439 + 101449 = 101888
  • 541 + 101347 = 101888

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 101,888 and was likely granted around 1870.

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