Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86770, here are decompositions:

3 + 86767 = 86770
17 + 86753 = 86770
41 + 86729 = 86770
59 + 86711 = 86770
191 + 86579 = 86770
197 + 86573 = 86770
239 + 86531 = 86770
269 + 86501 = 86770

Showing the first eight; more decompositions exist.
