Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468240, here are decompositions:

  • 17 + 31468223 = 31468240
  • 29 + 31468211 = 31468240
  • 71 + 31468169 = 31468240
  • 173 + 31468067 = 31468240
  • 227 + 31468013 = 31468240
  • 239 + 31468001 = 31468240
  • 257 + 31467983 = 31468240
  • 347 + 31467893 = 31468240

Showing the first eight; more decompositions exist.
