Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532678, here are decompositions:

  • 19 + 31532659 = 31532678
  • 97 + 31532581 = 31532678
  • 127 + 31532551 = 31532678
  • 139 + 31532539 = 31532678
  • 157 + 31532521 = 31532678
  • 181 + 31532497 = 31532678
  • 241 + 31532437 = 31532678
  • 277 + 31532401 = 31532678

Showing the first eight; more decompositions exist.
