Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484388, here are decompositions:

11 + 2147484377 = 2147484388
149 + 2147484239 = 2147484388
167 + 2147484221 = 2147484388
191 + 2147484197 = 2147484388
227 + 2147484161 = 2147484388
347 + 2147484041 = 2147484388
389 + 2147483999 = 2147484388
521 + 2147483867 = 2147484388

Showing the first eight; more decompositions exist.
