Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123824, here are decompositions:

3 + 123821 = 123824
7 + 123817 = 123824
37 + 123787 = 123824
67 + 123757 = 123824
97 + 123727 = 123824
157 + 123667 = 123824
163 + 123661 = 123824
193 + 123631 = 123824

Showing the first eight; more decompositions exist.
