Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123828, here are decompositions:

7 + 123821 = 123828
11 + 123817 = 123828
37 + 123791 = 123828
41 + 123787 = 123828
71 + 123757 = 123828
97 + 123731 = 123828
101 + 123727 = 123828
109 + 123719 = 123828

Showing the first eight; more decompositions exist.
