Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499428, here are decompositions:

37 + 2147499391 = 2147499428
79 + 2147499349 = 2147499428
211 + 2147499217 = 2147499428
337 + 2147499091 = 2147499428
601 + 2147498827 = 2147499428
631 + 2147498797 = 2147499428
661 + 2147498767 = 2147499428
691 + 2147498737 = 2147499428

Showing the first eight; more decompositions exist.
