Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22122, here are decompositions:

11 + 22111 = 22122
13 + 22109 = 22122
29 + 22093 = 22122
31 + 22091 = 22122
43 + 22079 = 22122
59 + 22063 = 22122
71 + 22051 = 22122
83 + 22039 = 22122

Showing the first eight; more decompositions exist.
