Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468780, here are decompositions:

  • 7 + 2147468773 = 2147468780
  • 181 + 2147468599 = 2147468780
  • 277 + 2147468503 = 2147468780
  • 283 + 2147468497 = 2147468780
  • 337 + 2147468443 = 2147468780
  • 349 + 2147468431 = 2147468780
  • 439 + 2147468341 = 2147468780
  • 463 + 2147468317 = 2147468780

Showing the first eight; more decompositions exist.
