Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484260, here are decompositions:

37 + 2147484223 = 2147484260
151 + 2147484109 = 2147484260
199 + 2147484061 = 2147484260
223 + 2147484037 = 2147484260
331 + 2147483929 = 2147484260
367 + 2147483893 = 2147484260
373 + 2147483887 = 2147484260
547 + 2147483713 = 2147484260

Showing the first eight; more decompositions exist.
