Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538738, here are decompositions:

17 + 538721 = 538738
29 + 538709 = 538738
41 + 538697 = 538738
89 + 538649 = 538738
149 + 538589 = 538738
227 + 538511 = 538738
251 + 538487 = 538738
257 + 538481 = 538738

Showing the first eight; more decompositions exist.
