Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147583960, here are decompositions:

  • 13 + 2147583947 = 2147583960
  • 17 + 2147583943 = 2147583960
  • 23 + 2147583937 = 2147583960
  • 37 + 2147583923 = 2147583960
  • 97 + 2147583863 = 2147583960
  • 127 + 2147583833 = 2147583960
  • 131 + 2147583829 = 2147583960
  • 167 + 2147583793 = 2147583960

Showing the first eight; more decompositions exist.
