Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617088, here are decompositions:

  • 11 + 31617077 = 31617088
  • 59 + 31617029 = 31617088
  • 89 + 31616999 = 31617088
  • 101 + 31616987 = 31617088
  • 137 + 31616951 = 31617088
  • 197 + 31616891 = 31617088
  • 359 + 31616729 = 31617088
  • 401 + 31616687 = 31617088

Showing the first eight; more decompositions exist.
