Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617396, here are decompositions:

  • 17 + 31617379 = 31617396
  • 23 + 31617373 = 31617396
  • 67 + 31617329 = 31617396
  • 103 + 31617293 = 31617396
  • 113 + 31617283 = 31617396
  • 127 + 31617269 = 31617396
  • 157 + 31617239 = 31617396
  • 197 + 31617199 = 31617396

Showing the first eight; more decompositions exist.
