Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499470, here are decompositions:

  • 13 + 2147499457 = 2147499470
  • 19 + 2147499451 = 2147499470
  • 37 + 2147499433 = 2147499470
  • 79 + 2147499391 = 2147499470
  • 229 + 2147499241 = 2147499470
  • 331 + 2147499139 = 2147499470
  • 379 + 2147499091 = 2147499470
  • 433 + 2147499037 = 2147499470

Showing the first eight; more decompositions exist.
