Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7816, here are decompositions:

23 + 7793 = 7816
59 + 7757 = 7816
89 + 7727 = 7816
113 + 7703 = 7816
167 + 7649 = 7816
173 + 7643 = 7816
227 + 7589 = 7816
233 + 7583 = 7816

Showing the first eight; more decompositions exist.
