Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121708, here are decompositions:

11 + 121697 = 121708
47 + 121661 = 121708
71 + 121637 = 121708
101 + 121607 = 121708
131 + 121577 = 121708
137 + 121571 = 121708
149 + 121559 = 121708
239 + 121469 = 121708

Showing the first eight; more decompositions exist.
