Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123150, here are decompositions:

7 + 123143 = 123150
23 + 123127 = 123150
29 + 123121 = 123150
37 + 123113 = 123150
59 + 123091 = 123150
67 + 123083 = 123150
73 + 123077 = 123150
101 + 123049 = 123150

Showing the first eight; more decompositions exist.
