Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51942, here are decompositions:

13 + 51929 = 51942
29 + 51913 = 51942
43 + 51899 = 51942
71 + 51871 = 51942
73 + 51869 = 51942
83 + 51859 = 51942
89 + 51853 = 51942
103 + 51839 = 51942

Showing the first eight; more decompositions exist.
