Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30822, here are decompositions:

5 + 30817 = 30822
13 + 30809 = 30822
19 + 30803 = 30822
41 + 30781 = 30822
59 + 30763 = 30822
109 + 30713 = 30822
151 + 30671 = 30822
173 + 30649 = 30822

Showing the first eight; more decompositions exist.
