Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584730, here are decompositions:

37 + 2147584693 = 2147584730
61 + 2147584669 = 2147584730
73 + 2147584657 = 2147584730
79 + 2147584651 = 2147584730
127 + 2147584603 = 2147584730
211 + 2147584519 = 2147584730
229 + 2147584501 = 2147584730
337 + 2147584393 = 2147584730

Showing the first eight; more decompositions exist.
