Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78810, here are decompositions:

7 + 78803 = 78810
13 + 78797 = 78810
19 + 78791 = 78810
23 + 78787 = 78810
29 + 78781 = 78810
31 + 78779 = 78810
73 + 78737 = 78810
89 + 78721 = 78810

Showing the first eight; more decompositions exist.
