Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492934, here are decompositions:

5 + 2147492929 = 2147492934
11 + 2147492923 = 2147492934
193 + 2147492741 = 2147492934
233 + 2147492701 = 2147492934
263 + 2147492671 = 2147492934
281 + 2147492653 = 2147492934
313 + 2147492621 = 2147492934
337 + 2147492597 = 2147492934

Showing the first eight; more decompositions exist.
