Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488470, here are decompositions:

41 + 2147488429 = 2147488470
53 + 2147488417 = 2147488470
59 + 2147488411 = 2147488470
89 + 2147488381 = 2147488470
137 + 2147488333 = 2147488470
163 + 2147488307 = 2147488470
191 + 2147488279 = 2147488470
223 + 2147488247 = 2147488470

Showing the first eight; more decompositions exist.
