Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567528, here are decompositions:

  • 17 + 31567511 = 31567528
  • 101 + 31567427 = 31567528
  • 131 + 31567397 = 31567528
  • 257 + 31567271 = 31567528
  • 479 + 31567049 = 31567528
  • 617 + 31566911 = 31567528
  • 701 + 31566827 = 31567528
  • 929 + 31566599 = 31567528

Showing the first eight; more decompositions exist.
