Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467904, here are decompositions:

  • 5 + 31467899 = 31467904
  • 11 + 31467893 = 31467904
  • 137 + 31467767 = 31467904
  • 227 + 31467677 = 31467904
  • 257 + 31467647 = 31467904
  • 311 + 31467593 = 31467904
  • 317 + 31467587 = 31467904
  • 353 + 31467551 = 31467904

Showing the first eight; more decompositions exist.
