Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156822, here are decompositions:

5 + 156817 = 156822
23 + 156799 = 156822
41 + 156781 = 156822
73 + 156749 = 156822
89 + 156733 = 156822
103 + 156719 = 156822
131 + 156691 = 156822
139 + 156683 = 156822

Showing the first eight; more decompositions exist.
