Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123124, here are decompositions:

3 + 123121 = 123124
11 + 123113 = 123124
41 + 123083 = 123124
47 + 123077 = 123124
107 + 123017 = 123124
167 + 122957 = 123124
233 + 122891 = 123124
257 + 122867 = 123124

Showing the first eight; more decompositions exist.
