Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544994, here are decompositions:

  • 31 + 31544963 = 31544994
  • 53 + 31544941 = 31544994
  • 71 + 31544923 = 31544994
  • 137 + 31544857 = 31544994
  • 167 + 31544827 = 31544994
  • 211 + 31544783 = 31544994
  • 223 + 31544771 = 31544994
  • 277 + 31544717 = 31544994

Showing the first eight; more decompositions exist.
