Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51066, here are decompositions:

5 + 51061 = 51066
7 + 51059 = 51066
19 + 51047 = 51066
23 + 51043 = 51066
73 + 50993 = 51066
97 + 50969 = 51066
109 + 50957 = 51066
137 + 50929 = 51066

Showing the first eight; more decompositions exist.
