Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491282, here are decompositions:

5 + 2147491277 = 2147491282
59 + 2147491223 = 2147491282
89 + 2147491193 = 2147491282
191 + 2147491091 = 2147491282
239 + 2147491043 = 2147491282
263 + 2147491019 = 2147491282
281 + 2147491001 = 2147491282
359 + 2147490923 = 2147491282

Showing the first eight; more decompositions exist.
