Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468474, here are decompositions:

  • 31 + 2147468443 = 2147468474
  • 43 + 2147468431 = 2147468474
  • 157 + 2147468317 = 2147468474
  • 241 + 2147468233 = 2147468474
  • 661 + 2147467813 = 2147468474
  • 673 + 2147467801 = 2147468474
  • 727 + 2147467747 = 2147468474
  • 757 + 2147467717 = 2147468474

Showing the first eight; more decompositions exist.
