Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493454, here are decompositions:

173 + 2147493281 = 2147493454
401 + 2147493053 = 2147493454
857 + 2147492597 = 2147493454
863 + 2147492591 = 2147493454
1061 + 2147492393 = 2147493454
1193 + 2147492261 = 2147493454
1223 + 2147492231 = 2147493454
1493 + 2147491961 = 2147493454

Showing the first eight; more decompositions exist.
