Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123242, here are decompositions:

3 + 123239 = 123242
13 + 123229 = 123242
73 + 123169 = 123242
151 + 123091 = 123242
193 + 123049 = 123242
211 + 123031 = 123242
241 + 123001 = 123242
271 + 122971 = 123242

Showing the first eight; more decompositions exist.
