Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468808, here are decompositions:

  • 5 + 2147468803 = 2147468808
  • 7 + 2147468801 = 2147468808
  • 29 + 2147468779 = 2147468808
  • 157 + 2147468651 = 2147468808
  • 271 + 2147468537 = 2147468808
  • 311 + 2147468497 = 2147468808
  • 379 + 2147468429 = 2147468808
  • 467 + 2147468341 = 2147468808

Showing the first eight; more decompositions exist.
