Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123924, here are decompositions:

13 + 123911 = 123924
37 + 123887 = 123924
61 + 123863 = 123924
71 + 123853 = 123924
103 + 123821 = 123924
107 + 123817 = 123924
137 + 123787 = 123924
167 + 123757 = 123924

Showing the first eight; more decompositions exist.
