Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490478, here are decompositions:

  • 239 + 2147490239 = 2147490478
  • 317 + 2147490161 = 2147490478
  • 389 + 2147490089 = 2147490478
  • 401 + 2147490077 = 2147490478
  • 467 + 2147490011 = 2147490478
  • 509 + 2147489969 = 2147490478
  • 521 + 2147489957 = 2147490478
  • 569 + 2147489909 = 2147490478

Showing the first eight; more decompositions exist.
