Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491092, here are decompositions:

11 + 2147491081 = 2147491092
23 + 2147491069 = 2147491092
31 + 2147491061 = 2147491092
59 + 2147491033 = 2147491092
73 + 2147491019 = 2147491092
139 + 2147490953 = 2147491092
193 + 2147490899 = 2147491092
281 + 2147490811 = 2147491092

Showing the first eight; more decompositions exist.
