Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519338, here are decompositions:

  • 17 + 31519321 = 31519338
  • 31 + 31519307 = 31519338
  • 41 + 31519297 = 31519338
  • 127 + 31519211 = 31519338
  • 139 + 31519199 = 31519338
  • 157 + 31519181 = 31519338
  • 197 + 31519141 = 31519338
  • 229 + 31519109 = 31519338

Showing the first eight; more decompositions exist.
