Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123144, here are decompositions:

17 + 123127 = 123144
23 + 123121 = 123144
31 + 123113 = 123144
53 + 123091 = 123144
61 + 123083 = 123144
67 + 123077 = 123144
113 + 123031 = 123144
127 + 123017 = 123144

Showing the first eight; more decompositions exist.
