Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25822, here are decompositions:

3 + 25819 = 25822
23 + 25799 = 25822
29 + 25793 = 25822
59 + 25763 = 25822
89 + 25733 = 25822
149 + 25673 = 25822
179 + 25643 = 25822
233 + 25589 = 25822

Showing the first eight; more decompositions exist.
