Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156222, here are decompositions:

5 + 156217 = 156222
71 + 156151 = 156222
83 + 156139 = 156222
103 + 156119 = 156222
113 + 156109 = 156222
151 + 156071 = 156222
163 + 156059 = 156222
181 + 156041 = 156222

Showing the first eight; more decompositions exist.
