Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51946, here are decompositions:

5 + 51941 = 51946
17 + 51929 = 51946
47 + 51899 = 51946
53 + 51893 = 51946
107 + 51839 = 51946
149 + 51797 = 51946
179 + 51767 = 51946
197 + 51749 = 51946

Showing the first eight; more decompositions exist.
