Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468810, here are decompositions:

  • 7 + 2147468803 = 2147468810
  • 31 + 2147468779 = 2147468810
  • 37 + 2147468773 = 2147468810
  • 211 + 2147468599 = 2147468810
  • 307 + 2147468503 = 2147468810
  • 313 + 2147468497 = 2147468810
  • 367 + 2147468443 = 2147468810
  • 379 + 2147468431 = 2147468810

Showing the first eight; more decompositions exist.
