Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584002, here are decompositions:

  • 13 + 2147583989 = 2147584002
  • 19 + 2147583983 = 2147584002
  • 41 + 2147583961 = 2147584002
  • 59 + 2147583943 = 2147584002
  • 79 + 2147583923 = 2147584002
  • 139 + 2147583863 = 2147584002
  • 173 + 2147583829 = 2147584002
  • 229 + 2147583773 = 2147584002

Showing the first eight; more decompositions exist.
