Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567246, here are decompositions:

  • 5 + 31567241 = 31567246
  • 89 + 31567157 = 31567246
  • 197 + 31567049 = 31567246
  • 383 + 31566863 = 31567246
  • 419 + 31566827 = 31567246
  • 443 + 31566803 = 31567246
  • 449 + 31566797 = 31567246
  • 509 + 31566737 = 31567246

Showing the first eight; more decompositions exist.
