Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7810, here are decompositions:

17 + 7793 = 7810
53 + 7757 = 7810
83 + 7727 = 7810
107 + 7703 = 7810
137 + 7673 = 7810
167 + 7643 = 7810
227 + 7583 = 7810
233 + 7577 = 7810

Showing the first eight; more decompositions exist.
