Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156998, here are decompositions:

  • 19 + 156979 = 156998
  • 31 + 156967 = 156998
  • 97 + 156901 = 156998
  • 157 + 156841 = 156998
  • 181 + 156817 = 156998
  • 199 + 156799 = 156998
  • 271 + 156727 = 156998
  • 307 + 156691 = 156998

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 156,998 and was likely granted around 1873.

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