Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492398, here are decompositions:

5 + 2147492393 = 2147492398
11 + 2147492387 = 2147492398
59 + 2147492339 = 2147492398
71 + 2147492327 = 2147492398
101 + 2147492297 = 2147492398
137 + 2147492261 = 2147492398
167 + 2147492231 = 2147492398
239 + 2147492159 = 2147492398

Showing the first eight; more decompositions exist.
