Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538722, here are decompositions:

11 + 538711 = 538722
13 + 538709 = 538722
71 + 538651 = 538722
73 + 538649 = 538722
101 + 538621 = 538722
193 + 538529 = 538722
199 + 538523 = 538722
211 + 538511 = 538722

Showing the first eight; more decompositions exist.
