Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82564, here are decompositions:

3 + 82561 = 82564
5 + 82559 = 82564
71 + 82493 = 82564
101 + 82463 = 82564
107 + 82457 = 82564
191 + 82373 = 82564
257 + 82307 = 82564
263 + 82301 = 82564

Showing the first eight; more decompositions exist.
