Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485944, here are decompositions:

5 + 2147485939 = 2147485944
17 + 2147485927 = 2147485944
31 + 2147485913 = 2147485944
47 + 2147485897 = 2147485944
67 + 2147485877 = 2147485944
73 + 2147485871 = 2147485944
83 + 2147485861 = 2147485944
101 + 2147485843 = 2147485944

Showing the first eight; more decompositions exist.

IPv4 address
