Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576948, here are decompositions:

  • 17 + 31576931 = 31576948
  • 47 + 31576901 = 31576948
  • 59 + 31576889 = 31576948
  • 197 + 31576751 = 31576948
  • 239 + 31576709 = 31576948
  • 419 + 31576529 = 31576948
  • 509 + 31576439 = 31576948
  • 521 + 31576427 = 31576948

Showing the first eight; more decompositions exist.
