Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123880, here are decompositions:

17 + 123863 = 123880
47 + 123833 = 123880
59 + 123821 = 123880
89 + 123791 = 123880
149 + 123731 = 123880
173 + 123707 = 123880
179 + 123701 = 123880
227 + 123653 = 123880

Showing the first eight; more decompositions exist.
