Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492308, here are decompositions:

11 + 2147492297 = 2147492308
47 + 2147492261 = 2147492308
149 + 2147492159 = 2147492308
239 + 2147492069 = 2147492308
347 + 2147491961 = 2147492308
617 + 2147491691 = 2147492308
701 + 2147491607 = 2147492308
761 + 2147491547 = 2147492308

Showing the first eight; more decompositions exist.
