Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72222, here are decompositions:

11 + 72211 = 72222
53 + 72169 = 72222
61 + 72161 = 72222
83 + 72139 = 72222
113 + 72109 = 72222
131 + 72091 = 72222
149 + 72073 = 72222
179 + 72043 = 72222

Showing the first eight; more decompositions exist.
