Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470922, here are decompositions:

  • 19 + 2147470903 = 2147470922
  • 31 + 2147470891 = 2147470922
  • 151 + 2147470771 = 2147470922
  • 199 + 2147470723 = 2147470922
  • 409 + 2147470513 = 2147470922
  • 673 + 2147470249 = 2147470922
  • 739 + 2147470183 = 2147470922
  • 811 + 2147470111 = 2147470922

Showing the first eight; more decompositions exist.
