Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72824, here are decompositions:

7 + 72817 = 72824
61 + 72763 = 72824
97 + 72727 = 72824
151 + 72673 = 72824
163 + 72661 = 72824
181 + 72643 = 72824
211 + 72613 = 72824
277 + 72547 = 72824

Showing the first eight; more decompositions exist.
