Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600960, here are decompositions:

  • 3 + 31600957 = 31600960
  • 101 + 31600859 = 31600960
  • 137 + 31600823 = 31600960
  • 227 + 31600733 = 31600960
  • 239 + 31600721 = 31600960
  • 257 + 31600703 = 31600960
  • 431 + 31600529 = 31600960
  • 449 + 31600511 = 31600960

Showing the first eight; more decompositions exist.
