Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544966, here are decompositions:

  • 3 + 31544963 = 31544966
  • 43 + 31544923 = 31544966
  • 67 + 31544899 = 31544966
  • 109 + 31544857 = 31544966
  • 139 + 31544827 = 31544966
  • 379 + 31544587 = 31544966
  • 433 + 31544533 = 31544966
  • 457 + 31544509 = 31544966

Showing the first eight; more decompositions exist.
