Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51006, here are decompositions:

5 + 51001 = 51006
13 + 50993 = 51006
17 + 50989 = 51006
37 + 50969 = 51006
83 + 50923 = 51006
97 + 50909 = 51006
113 + 50893 = 51006
139 + 50867 = 51006

Showing the first eight; more decompositions exist.
