Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123270, here are decompositions:

11 + 123259 = 123270
31 + 123239 = 123270
41 + 123229 = 123270
53 + 123217 = 123270
61 + 123209 = 123270
67 + 123203 = 123270
79 + 123191 = 123270
101 + 123169 = 123270

Showing the first eight; more decompositions exist.
