Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123946, here are decompositions:

5 + 123941 = 123946
23 + 123923 = 123946
59 + 123887 = 123946
83 + 123863 = 123946
113 + 123833 = 123946
227 + 123719 = 123946
239 + 123707 = 123946
269 + 123677 = 123946

Showing the first eight; more decompositions exist.
