Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123916, here are decompositions:

5 + 123911 = 123916
29 + 123887 = 123916
53 + 123863 = 123916
83 + 123833 = 123916
113 + 123803 = 123916
179 + 123737 = 123916
197 + 123719 = 123916
239 + 123677 = 123916

Showing the first eight; more decompositions exist.
