Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123994, here are decompositions:

5 + 123989 = 123994
11 + 123983 = 123994
41 + 123953 = 123994
53 + 123941 = 123994
71 + 123923 = 123994
83 + 123911 = 123994
107 + 123887 = 123994
131 + 123863 = 123994

Showing the first eight; more decompositions exist.
