Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497948, here are decompositions:

5 + 2147497943 = 2147497948
41 + 2147497907 = 2147497948
47 + 2147497901 = 2147497948
59 + 2147497889 = 2147497948
179 + 2147497769 = 2147497948
191 + 2147497757 = 2147497948
251 + 2147497697 = 2147497948
257 + 2147497691 = 2147497948

Showing the first eight; more decompositions exist.
