Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978200, here are decompositions:

  • 19 + 978181 = 978200
  • 43 + 978157 = 978200
  • 109 + 978091 = 978200
  • 127 + 978073 = 978200
  • 151 + 978049 = 978200
  • 163 + 978037 = 978200
  • 193 + 978007 = 978200
  • 199 + 978001 = 978200

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 978,200 and was likely granted around 1910.

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