Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123768, here are decompositions:

11 + 123757 = 123768
31 + 123737 = 123768
37 + 123731 = 123768
41 + 123727 = 123768
61 + 123707 = 123768
67 + 123701 = 123768
101 + 123667 = 123768
107 + 123661 = 123768

Showing the first eight; more decompositions exist.
