Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485758, here are decompositions:

71 + 2147485687 = 2147485758
109 + 2147485649 = 2147485758
167 + 2147485591 = 2147485758
191 + 2147485567 = 2147485758
199 + 2147485559 = 2147485758
211 + 2147485547 = 2147485758
241 + 2147485517 = 2147485758
307 + 2147485451 = 2147485758

Showing the first eight; more decompositions exist.
