Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538724, here are decompositions:

3 + 538721 = 538724
13 + 538711 = 538724
73 + 538651 = 538724
103 + 538621 = 538724
127 + 538597 = 538724
157 + 538567 = 538724
163 + 538561 = 538724
211 + 538513 = 538724

Showing the first eight; more decompositions exist.
