Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152724, here are decompositions:

7 + 152717 = 152724
43 + 152681 = 152724
53 + 152671 = 152724
67 + 152657 = 152724
83 + 152641 = 152724
101 + 152623 = 152724
107 + 152617 = 152724
127 + 152597 = 152724

Showing the first eight; more decompositions exist.
