Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51938, here are decompositions:

31 + 51907 = 51938
67 + 51871 = 51938
79 + 51859 = 51938
109 + 51829 = 51938
151 + 51787 = 51938
307 + 51631 = 51938
331 + 51607 = 51938
421 + 51517 = 51938

Showing the first eight; more decompositions exist.
