Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123846, here are decompositions:

13 + 123833 = 123846
17 + 123829 = 123846
29 + 123817 = 123846
43 + 123803 = 123846
59 + 123787 = 123846
89 + 123757 = 123846
109 + 123737 = 123846
113 + 123733 = 123846

Showing the first eight; more decompositions exist.
