Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86728, here are decompositions:

17 + 86711 = 86728
101 + 86627 = 86728
149 + 86579 = 86728
167 + 86561 = 86728
197 + 86531 = 86728
227 + 86501 = 86728
251 + 86477 = 86728
347 + 86381 = 86728

Showing the first eight; more decompositions exist.
