Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121970, here are decompositions:

3 + 121967 = 121970
7 + 121963 = 121970
19 + 121951 = 121970
61 + 121909 = 121970
103 + 121867 = 121970
127 + 121843 = 121970
181 + 121789 = 121970
283 + 121687 = 121970

Showing the first eight; more decompositions exist.
