Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123470, here are decompositions:

13 + 123457 = 123470
31 + 123439 = 123470
37 + 123433 = 123470
43 + 123427 = 123470
73 + 123397 = 123470
97 + 123373 = 123470
163 + 123307 = 123470
181 + 123289 = 123470

Showing the first eight; more decompositions exist.
