Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620272, here are decompositions:

5 + 8620267 = 8620272
13 + 8620259 = 8620272
41 + 8620231 = 8620272
53 + 8620219 = 8620272
61 + 8620211 = 8620272
83 + 8620189 = 8620272
113 + 8620159 = 8620272
131 + 8620141 = 8620272

Showing the first eight; more decompositions exist.
