Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123180, here are decompositions:

11 + 123169 = 123180
37 + 123143 = 123180
53 + 123127 = 123180
59 + 123121 = 123180
67 + 123113 = 123180
89 + 123091 = 123180
97 + 123083 = 123180
103 + 123077 = 123180

Showing the first eight; more decompositions exist.
