Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584724, here are decompositions:

31 + 2147584693 = 2147584724
67 + 2147584657 = 2147584724
73 + 2147584651 = 2147584724
127 + 2147584597 = 2147584724
223 + 2147584501 = 2147584724
331 + 2147584393 = 2147584724
601 + 2147584123 = 2147584724
661 + 2147584063 = 2147584724

Showing the first eight; more decompositions exist.
