Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121956, here are decompositions:

5 + 121951 = 121956
7 + 121949 = 121956
19 + 121937 = 121956
47 + 121909 = 121956
67 + 121889 = 121956
73 + 121883 = 121956
89 + 121867 = 121956
103 + 121853 = 121956

Showing the first eight; more decompositions exist.
