Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556616, here are decompositions:

  • 59 + 31556557 = 31556616
  • 79 + 31556537 = 31556616
  • 127 + 31556489 = 31556616
  • 137 + 31556479 = 31556616
  • 139 + 31556477 = 31556616
  • 149 + 31556467 = 31556616
  • 193 + 31556423 = 31556616
  • 199 + 31556417 = 31556616

Showing the first eight; more decompositions exist.
