Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22182, here are decompositions:

11 + 22171 = 22182
23 + 22159 = 22182
29 + 22153 = 22182
53 + 22129 = 22182
59 + 22123 = 22182
71 + 22111 = 22182
73 + 22109 = 22182
89 + 22093 = 22182

Showing the first eight; more decompositions exist.
