Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31822, here are decompositions:

5 + 31817 = 31822
23 + 31799 = 31822
29 + 31793 = 31822
53 + 31769 = 31822
71 + 31751 = 31822
101 + 31721 = 31822
173 + 31649 = 31822
179 + 31643 = 31822

Showing the first eight; more decompositions exist.
