Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562708, here are decompositions:

  • 31 + 31562677 = 31562708
  • 97 + 31562611 = 31562708
  • 157 + 31562551 = 31562708
  • 241 + 31562467 = 31562708
  • 277 + 31562431 = 31562708
  • 379 + 31562329 = 31562708
  • 409 + 31562299 = 31562708
  • 571 + 31562137 = 31562708

Showing the first eight; more decompositions exist.
