Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518326, here are decompositions:

  • 13 + 31518313 = 31518326
  • 67 + 31518259 = 31518326
  • 97 + 31518229 = 31518326
  • 163 + 31518163 = 31518326
  • 277 + 31518049 = 31518326
  • 373 + 31517953 = 31518326
  • 439 + 31517887 = 31518326
  • 577 + 31517749 = 31518326

Showing the first eight; more decompositions exist.
