Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597728, here are decompositions:

5 + 8597723 = 8597728
59 + 8597669 = 8597728
89 + 8597639 = 8597728
107 + 8597621 = 8597728
137 + 8597591 = 8597728
197 + 8597531 = 8597728
257 + 8597471 = 8597728
311 + 8597417 = 8597728

Showing the first eight; more decompositions exist.
