Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486194, here are decompositions:

47 + 2147486147 = 2147486194
83 + 2147486111 = 2147486194
173 + 2147486021 = 2147486194
281 + 2147485913 = 2147486194
317 + 2147485877 = 2147486194
353 + 2147485841 = 2147486194
521 + 2147485673 = 2147486194
647 + 2147485547 = 2147486194

Showing the first eight; more decompositions exist.
