Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18738, here are decompositions:

7 + 18731 = 18738
19 + 18719 = 18738
37 + 18701 = 18738
47 + 18691 = 18738
59 + 18679 = 18738
67 + 18671 = 18738
101 + 18637 = 18738
151 + 18587 = 18738

Showing the first eight; more decompositions exist.
