Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7822, here are decompositions:

5 + 7817 = 7822
29 + 7793 = 7822
131 + 7691 = 7822
149 + 7673 = 7822
173 + 7649 = 7822
179 + 7643 = 7822
233 + 7589 = 7822
239 + 7583 = 7822

Showing the first eight; more decompositions exist.
