Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491120, here are decompositions:

29 + 2147491091 = 2147491120
53 + 2147491067 = 2147491120
59 + 2147491061 = 2147491120
83 + 2147491037 = 2147491120
101 + 2147491019 = 2147491120
113 + 2147491007 = 2147491120
167 + 2147490953 = 2147491120
197 + 2147490923 = 2147491120

Showing the first eight; more decompositions exist.
