Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123360, here are decompositions:

19 + 123341 = 123360
37 + 123323 = 123360
53 + 123307 = 123360
71 + 123289 = 123360
101 + 123259 = 123360
131 + 123229 = 123360
151 + 123209 = 123360
157 + 123203 = 123360

Showing the first eight; more decompositions exist.
