Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491668, here are decompositions:

59 + 2147491609 = 2147491668
61 + 2147491607 = 2147491668
71 + 2147491597 = 2147491668
109 + 2147491559 = 2147491668
131 + 2147491537 = 2147491668
151 + 2147491517 = 2147491668
191 + 2147491477 = 2147491668
251 + 2147491417 = 2147491668

Showing the first eight; more decompositions exist.
