Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557046, here are decompositions:

  • 23 + 31557023 = 31557046
  • 89 + 31556957 = 31557046
  • 107 + 31556939 = 31557046
  • 137 + 31556909 = 31557046
  • 233 + 31556813 = 31557046
  • 359 + 31556687 = 31557046
  • 509 + 31556537 = 31557046
  • 557 + 31556489 = 31557046

Showing the first eight; more decompositions exist.
