Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520624, here are decompositions:

  • 7 + 31520617 = 31520624
  • 43 + 31520581 = 31520624
  • 97 + 31520527 = 31520624
  • 127 + 31520497 = 31520624
  • 271 + 31520353 = 31520624
  • 307 + 31520317 = 31520624
  • 607 + 31520017 = 31520624
  • 613 + 31520011 = 31520624

Showing the first eight; more decompositions exist.
