Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123162, here are decompositions:

19 + 123143 = 123162
41 + 123121 = 123162
71 + 123091 = 123162
79 + 123083 = 123162
103 + 123059 = 123162
113 + 123049 = 123162
131 + 123031 = 123162
191 + 122971 = 123162

Showing the first eight; more decompositions exist.
