Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498742, here are decompositions:

5 + 2147498737 = 2147498742
13 + 2147498729 = 2147498742
19 + 2147498723 = 2147498742
83 + 2147498659 = 2147498742
89 + 2147498653 = 2147498742
113 + 2147498629 = 2147498742
149 + 2147498593 = 2147498742
199 + 2147498543 = 2147498742

Showing the first eight; more decompositions exist.
