Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491180, here are decompositions:

41 + 2147491139 = 2147491180
53 + 2147491127 = 2147491180
89 + 2147491091 = 2147491180
113 + 2147491067 = 2147491180
137 + 2147491043 = 2147491180
173 + 2147491007 = 2147491180
179 + 2147491001 = 2147491180
227 + 2147490953 = 2147491180

Showing the first eight; more decompositions exist.
