Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492686, here are decompositions:

47 + 2147492639 = 2147492686
89 + 2147492597 = 2147492686
197 + 2147492489 = 2147492686
239 + 2147492447 = 2147492686
257 + 2147492429 = 2147492686
293 + 2147492393 = 2147492686
347 + 2147492339 = 2147492686
359 + 2147492327 = 2147492686

Showing the first eight; more decompositions exist.
