Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499390, here are decompositions:

11 + 2147499379 = 2147499390
41 + 2147499349 = 2147499390
67 + 2147499323 = 2147499390
79 + 2147499311 = 2147499390
97 + 2147499293 = 2147499390
107 + 2147499283 = 2147499390
109 + 2147499281 = 2147499390
137 + 2147499253 = 2147499390

Showing the first eight; more decompositions exist.
