Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492782, here are decompositions:

23 + 2147492759 = 2147492782
41 + 2147492741 = 2147492782
173 + 2147492609 = 2147492782
191 + 2147492591 = 2147492782
293 + 2147492489 = 2147492782
353 + 2147492429 = 2147492782
389 + 2147492393 = 2147492782
443 + 2147492339 = 2147492782

Showing the first eight; more decompositions exist.
