Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491618, here are decompositions:

11 + 2147491607 = 2147491618
59 + 2147491559 = 2147491618
71 + 2147491547 = 2147491618
101 + 2147491517 = 2147491618
257 + 2147491361 = 2147491618
269 + 2147491349 = 2147491618
401 + 2147491217 = 2147491618
479 + 2147491139 = 2147491618

Showing the first eight; more decompositions exist.
