Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538626, here are decompositions:

5 + 538621 = 538626
29 + 538597 = 538626
37 + 538589 = 538626
47 + 538579 = 538626
59 + 538567 = 538626
73 + 538553 = 538626
97 + 538529 = 538626
103 + 538523 = 538626

Showing the first eight; more decompositions exist.
