Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123210, here are decompositions:

7 + 123203 = 123210
19 + 123191 = 123210
41 + 123169 = 123210
67 + 123143 = 123210
83 + 123127 = 123210
89 + 123121 = 123210
97 + 123113 = 123210
127 + 123083 = 123210

Showing the first eight; more decompositions exist.
