Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489478, here are decompositions:

5 + 2147489473 = 2147489478
37 + 2147489441 = 2147489478
41 + 2147489437 = 2147489478
131 + 2147489347 = 2147489478
179 + 2147489299 = 2147489478
181 + 2147489297 = 2147489478
271 + 2147489207 = 2147489478
389 + 2147489089 = 2147489478

Showing the first eight; more decompositions exist.
