Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484884, here are decompositions:

7 + 2147484877 = 2147484884
151 + 2147484733 = 2147484884
163 + 2147484721 = 2147484884
271 + 2147484613 = 2147484884
283 + 2147484601 = 2147484884
331 + 2147484553 = 2147484884
367 + 2147484517 = 2147484884
547 + 2147484337 = 2147484884

Showing the first eight; more decompositions exist.
