Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491192, here are decompositions:

53 + 2147491139 = 2147491192
101 + 2147491091 = 2147491192
131 + 2147491061 = 2147491192
149 + 2147491043 = 2147491192
173 + 2147491019 = 2147491192
191 + 2147491001 = 2147491192
239 + 2147490953 = 2147491192
269 + 2147490923 = 2147491192

Showing the first eight; more decompositions exist.
