Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539726, here are decompositions:

  • 13 + 31539713 = 31539726
  • 19 + 31539707 = 31539726
  • 67 + 31539659 = 31539726
  • 83 + 31539643 = 31539726
  • 139 + 31539587 = 31539726
  • 157 + 31539569 = 31539726
  • 227 + 31539499 = 31539726
  • 313 + 31539413 = 31539726

Showing the first eight; more decompositions exist.
