Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538746, here are decompositions:

7 + 538739 = 538746
23 + 538723 = 538746
37 + 538709 = 538746
97 + 538649 = 538746
149 + 538597 = 538746
157 + 538589 = 538746
167 + 538579 = 538746
179 + 538567 = 538746

Showing the first eight; more decompositions exist.
