Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484158, here are decompositions:

97 + 2147484061 = 2147484158
151 + 2147484007 = 2147484158
229 + 2147483929 = 2147484158
271 + 2147483887 = 2147484158
499 + 2147483659 = 2147484158
571 + 2147483587 = 2147484158
661 + 2147483497 = 2147484158
1021 + 2147483137 = 2147484158

Showing the first eight; more decompositions exist.
