Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538750, here are decompositions:

11 + 538739 = 538750
29 + 538721 = 538750
41 + 538709 = 538750
53 + 538697 = 538750
101 + 538649 = 538750
197 + 538553 = 538750
227 + 538523 = 538750
239 + 538511 = 538750

Showing the first eight; more decompositions exist.
