Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584056, here are decompositions:

  • 43 + 2147584013 = 2147584056
  • 67 + 2147583989 = 2147584056
  • 73 + 2147583983 = 2147584056
  • 89 + 2147583967 = 2147584056
  • 109 + 2147583947 = 2147584056
  • 113 + 2147583943 = 2147584056
  • 193 + 2147583863 = 2147584056
  • 223 + 2147583833 = 2147584056

Showing the first eight; more decompositions exist.
