Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123386, here are decompositions:

7 + 123379 = 123386
13 + 123373 = 123386
79 + 123307 = 123386
97 + 123289 = 123386
127 + 123259 = 123386
157 + 123229 = 123386
337 + 123049 = 123386
379 + 123007 = 123386

Showing the first eight; more decompositions exist.
