Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544974, here are decompositions:

  • 5 + 31544969 = 31544974
  • 11 + 31544963 = 31544974
  • 191 + 31544783 = 31544974
  • 257 + 31544717 = 31544974
  • 317 + 31544657 = 31544974
  • 401 + 31544573 = 31544974
  • 431 + 31544543 = 31544974
  • 443 + 31544531 = 31544974

Showing the first eight; more decompositions exist.
