Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123884, here are decompositions:

31 + 123853 = 123884
67 + 123817 = 123884
97 + 123787 = 123884
127 + 123757 = 123884
151 + 123733 = 123884
157 + 123727 = 123884
223 + 123661 = 123884
283 + 123601 = 123884

Showing the first eight; more decompositions exist.
