Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123930, here are decompositions:

7 + 123923 = 123930
19 + 123911 = 123930
43 + 123887 = 123930
67 + 123863 = 123930
97 + 123833 = 123930
101 + 123829 = 123930
109 + 123821 = 123930
113 + 123817 = 123930

Showing the first eight; more decompositions exist.
