Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123042, here are decompositions:

11 + 123031 = 123042
41 + 123001 = 123042
71 + 122971 = 123042
79 + 122963 = 123042
89 + 122953 = 123042
103 + 122939 = 123042
113 + 122929 = 123042
151 + 122891 = 123042

Showing the first eight; more decompositions exist.
