Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158724, here are decompositions:

61 + 158663 = 158724
67 + 158657 = 158724
103 + 158621 = 158724
107 + 158617 = 158724
113 + 158611 = 158724
127 + 158597 = 158724
151 + 158573 = 158724
157 + 158567 = 158724

Showing the first eight; more decompositions exist.
