Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66950, here are decompositions:

3 + 66947 = 66950
7 + 66943 = 66950
19 + 66931 = 66950
31 + 66919 = 66950
61 + 66889 = 66950
67 + 66883 = 66950
73 + 66877 = 66950
97 + 66853 = 66950

Showing the first eight; more decompositions exist.
