Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123290, here are decompositions:

31 + 123259 = 123290
61 + 123229 = 123290
73 + 123217 = 123290
163 + 123127 = 123290
199 + 123091 = 123290
241 + 123049 = 123290
283 + 123007 = 123290
337 + 122953 = 123290

Showing the first eight; more decompositions exist.
