Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568708, here are decompositions:

  • 7 + 31568701 = 31568708
  • 79 + 31568629 = 31568708
  • 97 + 31568611 = 31568708
  • 181 + 31568527 = 31568708
  • 211 + 31568497 = 31568708
  • 397 + 31568311 = 31568708
  • 421 + 31568287 = 31568708
  • 487 + 31568221 = 31568708

Showing the first eight; more decompositions exist.
