Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468446, here are decompositions:

  • 3 + 2147468443 = 2147468446
  • 17 + 2147468429 = 2147468446
  • 23 + 2147468423 = 2147468446
  • 29 + 2147468417 = 2147468446
  • 197 + 2147468249 = 2147468446
  • 257 + 2147468189 = 2147468446
  • 443 + 2147468003 = 2147468446
  • 479 + 2147467967 = 2147468446

Showing the first eight; more decompositions exist.
