Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556594, here are decompositions:

  • 37 + 31556557 = 31556594
  • 127 + 31556467 = 31556594
  • 241 + 31556353 = 31556594
  • 271 + 31556323 = 31556594
  • 613 + 31555981 = 31556594
  • 661 + 31555933 = 31556594
  • 673 + 31555921 = 31556594
  • 877 + 31555717 = 31556594

Showing the first eight; more decompositions exist.
