Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123774, here are decompositions:

17 + 123757 = 123774
37 + 123737 = 123774
41 + 123733 = 123774
43 + 123731 = 123774
47 + 123727 = 123774
67 + 123707 = 123774
73 + 123701 = 123774
97 + 123677 = 123774

Showing the first eight; more decompositions exist.
