Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578724, here are decompositions:

5 + 578719 = 578724
23 + 578701 = 578724
31 + 578693 = 578724
37 + 578687 = 578724
103 + 578621 = 578724
127 + 578597 = 578724
137 + 578587 = 578724
151 + 578573 = 578724

Showing the first eight; more decompositions exist.
