Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488278, here are decompositions:

29 + 2147488249 = 2147488278
31 + 2147488247 = 2147488278
107 + 2147488171 = 2147488278
127 + 2147488151 = 2147488278
167 + 2147488111 = 2147488278
211 + 2147488067 = 2147488278
251 + 2147488027 = 2147488278
269 + 2147488009 = 2147488278

Showing the first eight; more decompositions exist.
