Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491168, here are decompositions:

29 + 2147491139 = 2147491168
41 + 2147491127 = 2147491168
101 + 2147491067 = 2147491168
107 + 2147491061 = 2147491168
131 + 2147491037 = 2147491168
149 + 2147491019 = 2147491168
167 + 2147491001 = 2147491168
269 + 2147490899 = 2147491168

Showing the first eight; more decompositions exist.
