Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657746, here are decompositions:

23 + 8657723 = 8657746
47 + 8657699 = 8657746
59 + 8657687 = 8657746
107 + 8657639 = 8657746
113 + 8657633 = 8657746
179 + 8657567 = 8657746
233 + 8657513 = 8657746
359 + 8657387 = 8657746

Showing the first eight; more decompositions exist.
