Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538726, here are decompositions:

3 + 538723 = 538726
5 + 538721 = 538726
17 + 538709 = 538726
29 + 538697 = 538726
137 + 538589 = 538726
173 + 538553 = 538726
197 + 538529 = 538726
239 + 538487 = 538726

Showing the first eight; more decompositions exist.
