Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72152, here are decompositions:

13 + 72139 = 72152
43 + 72109 = 72152
61 + 72091 = 72152
79 + 72073 = 72152
109 + 72043 = 72152
181 + 71971 = 72152
211 + 71941 = 72152
271 + 71881 = 72152

Showing the first eight; more decompositions exist.
