Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123028, here are decompositions:

11 + 123017 = 123028
71 + 122957 = 123028
89 + 122939 = 123028
107 + 122921 = 123028
137 + 122891 = 123028
167 + 122861 = 123028
179 + 122849 = 123028
239 + 122789 = 123028

Showing the first eight; more decompositions exist.
