Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500724, here are decompositions:

5 + 500719 = 500724
11 + 500713 = 500724
31 + 500693 = 500724
47 + 500677 = 500724
53 + 500671 = 500724
137 + 500587 = 500724
157 + 500567 = 500724
197 + 500527 = 500724

Showing the first eight; more decompositions exist.
