Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489220, here are decompositions:

  • 13 + 2147489207 = 2147489220
  • 17 + 2147489203 = 2147489220
  • 131 + 2147489089 = 2147489220
  • 137 + 2147489083 = 2147489220
  • 197 + 2147489023 = 2147489220
  • 223 + 2147488997 = 2147489220
  • 307 + 2147488913 = 2147489220
  • 313 + 2147488907 = 2147489220

Showing the first eight; more decompositions exist.
