Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51010, here are decompositions:

17 + 50993 = 51010
41 + 50969 = 51010
53 + 50957 = 51010
59 + 50951 = 51010
101 + 50909 = 51010
137 + 50873 = 51010
233 + 50777 = 51010
257 + 50753 = 51010

Showing the first eight; more decompositions exist.
