Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574416, here are decompositions:

  • 47 + 31574369 = 31574416
  • 53 + 31574363 = 31574416
  • 89 + 31574327 = 31574416
  • 113 + 31574303 = 31574416
  • 317 + 31574099 = 31574416
  • 449 + 31573967 = 31574416
  • 557 + 31573859 = 31574416
  • 563 + 31573853 = 31574416

Showing the first eight; more decompositions exist.
