Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404142, here are decompositions:

43 + 2147404099 = 2147404142
283 + 2147403859 = 2147404142
613 + 2147403529 = 2147404142
673 + 2147403469 = 2147404142
733 + 2147403409 = 2147404142
739 + 2147403403 = 2147404142
859 + 2147403283 = 2147404142
1021 + 2147403121 = 2147404142

Showing the first eight; more decompositions exist.
