Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484378, here are decompositions:

29 + 2147484349 = 2147484378
41 + 2147484337 = 2147484378
47 + 2147484331 = 2147484378
101 + 2147484277 = 2147484378
107 + 2147484271 = 2147484378
139 + 2147484239 = 2147484378
157 + 2147484221 = 2147484378
181 + 2147484197 = 2147484378

Showing the first eight; more decompositions exist.
