Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7924, here are decompositions:

5 + 7919 = 7924
17 + 7907 = 7924
23 + 7901 = 7924
41 + 7883 = 7924
47 + 7877 = 7924
71 + 7853 = 7924
83 + 7841 = 7924
101 + 7823 = 7924

Showing the first eight; more decompositions exist.
