Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538620, here are decompositions:

23 + 538597 = 538620
31 + 538589 = 538620
41 + 538579 = 538620
53 + 538567 = 538620
59 + 538561 = 538620
67 + 538553 = 538620
97 + 538523 = 538620
101 + 538519 = 538620

Showing the first eight; more decompositions exist.
