Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123810, here are decompositions:

7 + 123803 = 123810
19 + 123791 = 123810
23 + 123787 = 123810
53 + 123757 = 123810
73 + 123737 = 123810
79 + 123731 = 123810
83 + 123727 = 123810
103 + 123707 = 123810

Showing the first eight; more decompositions exist.
