Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72822, here are decompositions:

5 + 72817 = 72822
59 + 72763 = 72822
83 + 72739 = 72822
89 + 72733 = 72822
103 + 72719 = 72822
149 + 72673 = 72822
151 + 72671 = 72822
173 + 72649 = 72822

Showing the first eight; more decompositions exist.
