Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76810, here are decompositions:

29 + 76781 = 76810
53 + 76757 = 76810
113 + 76697 = 76810
131 + 76679 = 76810
137 + 76673 = 76810
179 + 76631 = 76810
269 + 76541 = 76810
317 + 76493 = 76810

Showing the first eight; more decompositions exist.
