Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584068, here are decompositions:

5 + 2147584063 = 2147584068
11 + 2147584057 = 2147584068
79 + 2147583989 = 2147584068
101 + 2147583967 = 2147584068
107 + 2147583961 = 2147584068
131 + 2147583937 = 2147584068
239 + 2147583829 = 2147584068
269 + 2147583799 = 2147584068

Showing the first eight; more decompositions exist.
