Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72272, here are decompositions:

3 + 72269 = 72272
19 + 72253 = 72272
43 + 72229 = 72272
61 + 72211 = 72272
103 + 72169 = 72272
163 + 72109 = 72272
181 + 72091 = 72272
199 + 72073 = 72272

Showing the first eight; more decompositions exist.
