Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147556634, here are decompositions:

  • 131 + 2147556503 = 2147556634
  • 191 + 2147556443 = 2147556634
  • 227 + 2147556407 = 2147556634
  • 317 + 2147556317 = 2147556634
  • 491 + 2147556143 = 2147556634
  • 563 + 2147556071 = 2147556634
  • 683 + 2147555951 = 2147556634
  • 857 + 2147555777 = 2147556634

Showing the first eight; more decompositions exist.
