Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147448656, here are decompositions:

  • 79 + 2147448577 = 2147448656
  • 229 + 2147448427 = 2147448656
  • 277 + 2147448379 = 2147448656
  • 607 + 2147448049 = 2147448656
  • 643 + 2147448013 = 2147448656
  • 739 + 2147447917 = 2147448656
  • 757 + 2147447899 = 2147448656
  • 823 + 2147447833 = 2147448656

Showing the first eight; more decompositions exist.
