Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510196, here are decompositions:

  • 103 + 31510093 = 31510196
  • 229 + 31509967 = 31510196
  • 283 + 31509913 = 31510196
  • 307 + 31509889 = 31510196
  • 313 + 31509883 = 31510196
  • 379 + 31509817 = 31510196
  • 433 + 31509763 = 31510196
  • 439 + 31509757 = 31510196

Showing the first eight; more decompositions exist.
