Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488208, here are decompositions:

37 + 2147488171 = 2147488208
97 + 2147488111 = 2147488208
181 + 2147488027 = 2147488208
199 + 2147488009 = 2147488208
277 + 2147487931 = 2147488208
337 + 2147487871 = 2147488208
379 + 2147487829 = 2147488208
409 + 2147487799 = 2147488208

Showing the first eight; more decompositions exist.
