Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492788, here are decompositions:

29 + 2147492759 = 2147492788
47 + 2147492741 = 2147492788
149 + 2147492639 = 2147492788
167 + 2147492621 = 2147492788
179 + 2147492609 = 2147492788
191 + 2147492597 = 2147492788
197 + 2147492591 = 2147492788
359 + 2147492429 = 2147492788

Showing the first eight; more decompositions exist.
