Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121650, here are decompositions:

13 + 121637 = 121650
17 + 121633 = 121650
19 + 121631 = 121650
29 + 121621 = 121650
41 + 121609 = 121650
43 + 121607 = 121650
59 + 121591 = 121650
71 + 121579 = 121650

Showing the first eight; more decompositions exist.
