Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7950, here are decompositions:

13 + 7937 = 7950
17 + 7933 = 7950
23 + 7927 = 7950
31 + 7919 = 7950
43 + 7907 = 7950
67 + 7883 = 7950
71 + 7879 = 7950
73 + 7877 = 7950

Showing the first eight; more decompositions exist.
