Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469128, here are decompositions:

  • 7 + 469121 = 469128
  • 29 + 469099 = 469128
  • 59 + 469069 = 469128
  • 97 + 469031 = 469128
  • 229 + 468899 = 469128
  • 239 + 468889 = 469128
  • 241 + 468887 = 469128
  • 269 + 468859 = 469128

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 469,128 and was likely granted around 1891.

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