Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492440, here are decompositions:

11 + 2147492429 = 2147492440
47 + 2147492393 = 2147492440
53 + 2147492387 = 2147492440
101 + 2147492339 = 2147492440
113 + 2147492327 = 2147492440
179 + 2147492261 = 2147492440
257 + 2147492183 = 2147492440
281 + 2147492159 = 2147492440

Showing the first eight; more decompositions exist.
