Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485828, here are decompositions:

11 + 2147485817 = 2147485828
179 + 2147485649 = 2147485828
269 + 2147485559 = 2147485828
281 + 2147485547 = 2147485828
311 + 2147485517 = 2147485828
491 + 2147485337 = 2147485828
569 + 2147485259 = 2147485828
647 + 2147485181 = 2147485828

Showing the first eight; more decompositions exist.
