Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488040, here are decompositions:

13 + 2147488027 = 2147488040
31 + 2147488009 = 2147488040
109 + 2147487931 = 2147488040
211 + 2147487829 = 2147488040
223 + 2147487817 = 2147488040
241 + 2147487799 = 2147488040
283 + 2147487757 = 2147488040
337 + 2147487703 = 2147488040

Showing the first eight; more decompositions exist.
