Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493738, here are decompositions:

7 + 2147493731 = 2147493738
29 + 2147493709 = 2147493738
31 + 2147493707 = 2147493738
59 + 2147493679 = 2147493738
67 + 2147493671 = 2147493738
109 + 2147493629 = 2147493738
139 + 2147493599 = 2147493738
149 + 2147493589 = 2147493738

Showing the first eight; more decompositions exist.
