Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484812, here are decompositions:

61 + 2147484751 = 2147484812
79 + 2147484733 = 2147484812
199 + 2147484613 = 2147484812
211 + 2147484601 = 2147484812
271 + 2147484541 = 2147484812
313 + 2147484499 = 2147484812
373 + 2147484439 = 2147484812
379 + 2147484433 = 2147484812

Showing the first eight; more decompositions exist.
