Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488266, here are decompositions:

17 + 2147488249 = 2147488266
19 + 2147488247 = 2147488266
103 + 2147488163 = 2147488266
113 + 2147488153 = 2147488266
199 + 2147488067 = 2147488266
223 + 2147488043 = 2147488266
239 + 2147488027 = 2147488266
257 + 2147488009 = 2147488266

Showing the first eight; more decompositions exist.
