Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86782, here are decompositions:

11 + 86771 = 86782
29 + 86753 = 86782
53 + 86729 = 86782
71 + 86711 = 86782
89 + 86693 = 86782
251 + 86531 = 86782
281 + 86501 = 86782
359 + 86423 = 86782

Showing the first eight; more decompositions exist.
