Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123756, here are decompositions:

19 + 123737 = 123756
23 + 123733 = 123756
29 + 123727 = 123756
37 + 123719 = 123756
79 + 123677 = 123756
89 + 123667 = 123756
103 + 123653 = 123756
137 + 123619 = 123756

Showing the first eight; more decompositions exist.
