Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123928, here are decompositions:

5 + 123923 = 123928
17 + 123911 = 123928
41 + 123887 = 123928
107 + 123821 = 123928
137 + 123791 = 123928
191 + 123737 = 123928
197 + 123731 = 123928
227 + 123701 = 123928

Showing the first eight; more decompositions exist.
