Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490470, here are decompositions:

  • 7 + 2147490463 = 2147490470
  • 19 + 2147490451 = 2147490470
  • 109 + 2147490361 = 2147490470
  • 127 + 2147490343 = 2147490470
  • 241 + 2147490229 = 2147490470
  • 409 + 2147490061 = 2147490470
  • 523 + 2147489947 = 2147490470
  • 571 + 2147489899 = 2147490470

Showing the first eight; more decompositions exist.
