Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568624, here are decompositions:

  • 13 + 31568611 = 31568624
  • 37 + 31568587 = 31568624
  • 97 + 31568527 = 31568624
  • 127 + 31568497 = 31568624
  • 211 + 31568413 = 31568624
  • 271 + 31568353 = 31568624
  • 277 + 31568347 = 31568624
  • 313 + 31568311 = 31568624

Showing the first eight; more decompositions exist.
