Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7954, here are decompositions:

3 + 7951 = 7954
5 + 7949 = 7954
17 + 7937 = 7954
47 + 7907 = 7954
53 + 7901 = 7954
71 + 7883 = 7954
101 + 7853 = 7954
113 + 7841 = 7954

Showing the first eight; more decompositions exist.
