Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469866, here are decompositions:

37 + 2147469829 = 2147469866
43 + 2147469823 = 2147469866
163 + 2147469703 = 2147469866
229 + 2147469637 = 2147469866
313 + 2147469553 = 2147469866
709 + 2147469157 = 2147469866
733 + 2147469133 = 2147469866
859 + 2147469007 = 2147469866

Showing the first eight; more decompositions exist.
