Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122290, here are decompositions:

11 + 122279 = 122290
17 + 122273 = 122290
23 + 122267 = 122290
59 + 122231 = 122290
71 + 122219 = 122290
83 + 122207 = 122290
89 + 122201 = 122290
173 + 122117 = 122290

Showing the first eight; more decompositions exist.
