Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123860, here are decompositions:

7 + 123853 = 123860
31 + 123829 = 123860
43 + 123817 = 123860
73 + 123787 = 123860
103 + 123757 = 123860
127 + 123733 = 123860
193 + 123667 = 123860
199 + 123661 = 123860

Showing the first eight; more decompositions exist.
