Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122660, here are decompositions:

7 + 122653 = 122660
61 + 122599 = 122660
103 + 122557 = 122660
127 + 122533 = 122660
151 + 122509 = 122660
157 + 122503 = 122660
163 + 122497 = 122660
211 + 122449 = 122660

Showing the first eight; more decompositions exist.
