Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123130, here are decompositions:

3 + 123127 = 123130
17 + 123113 = 123130
47 + 123083 = 123130
53 + 123077 = 123130
71 + 123059 = 123130
113 + 123017 = 123130
167 + 122963 = 123130
173 + 122957 = 123130

Showing the first eight; more decompositions exist.
