Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485690, here are decompositions:

3 + 2147485687 = 2147485690
17 + 2147485673 = 2147485690
41 + 2147485649 = 2147485690
131 + 2147485559 = 2147485690
167 + 2147485523 = 2147485690
173 + 2147485517 = 2147485690
191 + 2147485499 = 2147485690
239 + 2147485451 = 2147485690

Showing the first eight; more decompositions exist.
