Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123894, here are decompositions:

7 + 123887 = 123894
31 + 123863 = 123894
41 + 123853 = 123894
61 + 123833 = 123894
73 + 123821 = 123894
103 + 123791 = 123894
107 + 123787 = 123894
137 + 123757 = 123894

Showing the first eight; more decompositions exist.
