Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538740, here are decompositions:

17 + 538723 = 538740
19 + 538721 = 538740
29 + 538711 = 538740
31 + 538709 = 538740
43 + 538697 = 538740
89 + 538651 = 538740
151 + 538589 = 538740
173 + 538567 = 538740

Showing the first eight; more decompositions exist.
