Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123218, here are decompositions:

97 + 123121 = 123218
127 + 123091 = 123218
211 + 123007 = 123218
331 + 122887 = 123218
349 + 122869 = 123218
379 + 122839 = 123218
457 + 122761 = 123218
499 + 122719 = 123218

Showing the first eight; more decompositions exist.
