Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501842, here are decompositions:

173 + 2147501669 = 2147501842
569 + 2147501273 = 2147501842
593 + 2147501249 = 2147501842
911 + 2147500931 = 2147501842
953 + 2147500889 = 2147501842
971 + 2147500871 = 2147501842
1061 + 2147500781 = 2147501842
1181 + 2147500661 = 2147501842

Showing the first eight; more decompositions exist.
