Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551676, here are decompositions:

  • 5 + 31551671 = 31551676
  • 47 + 31551629 = 31551676
  • 83 + 31551593 = 31551676
  • 89 + 31551587 = 31551676
  • 137 + 31551539 = 31551676
  • 173 + 31551503 = 31551676
  • 179 + 31551497 = 31551676
  • 239 + 31551437 = 31551676

Showing the first eight; more decompositions exist.
