Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123192, here are decompositions:

23 + 123169 = 123192
71 + 123121 = 123192
79 + 123113 = 123192
101 + 123091 = 123192
109 + 123083 = 123192
191 + 123001 = 123192
229 + 122963 = 123192
239 + 122953 = 123192

Showing the first eight; more decompositions exist.
