Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123132, here are decompositions:

5 + 123127 = 123132
11 + 123121 = 123132
19 + 123113 = 123132
41 + 123091 = 123132
73 + 123059 = 123132
83 + 123049 = 123132
101 + 123031 = 123132
131 + 123001 = 123132

Showing the first eight; more decompositions exist.
