Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123102, here are decompositions:

11 + 123091 = 123102
19 + 123083 = 123102
43 + 123059 = 123102
53 + 123049 = 123102
71 + 123031 = 123102
101 + 123001 = 123102
131 + 122971 = 123102
139 + 122963 = 123102

Showing the first eight; more decompositions exist.
