Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51930, here are decompositions:

17 + 51913 = 51930
23 + 51907 = 51930
31 + 51899 = 51930
37 + 51893 = 51930
59 + 51871 = 51930
61 + 51869 = 51930
71 + 51859 = 51930
101 + 51829 = 51930

Showing the first eight; more decompositions exist.
