Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7938, here are decompositions:

5 + 7933 = 7938
11 + 7927 = 7938
19 + 7919 = 7938
31 + 7907 = 7938
37 + 7901 = 7938
59 + 7879 = 7938
61 + 7877 = 7938
71 + 7867 = 7938

Showing the first eight; more decompositions exist.
