Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72264, here are decompositions:

11 + 72253 = 72264
13 + 72251 = 72264
37 + 72227 = 72264
41 + 72223 = 72264
43 + 72221 = 72264
53 + 72211 = 72264
97 + 72167 = 72264
103 + 72161 = 72264

Showing the first eight; more decompositions exist.
