Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86564, here are decompositions:

3 + 86561 = 86564
31 + 86533 = 86564
73 + 86491 = 86564
97 + 86467 = 86564
103 + 86461 = 86564
151 + 86413 = 86564
193 + 86371 = 86564
211 + 86353 = 86564

Showing the first eight; more decompositions exist.
