Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607628, here are decompositions:

41 + 8607587 = 8607628
89 + 8607539 = 8607628
149 + 8607479 = 8607628
179 + 8607449 = 8607628
251 + 8607377 = 8607628
257 + 8607371 = 8607628
347 + 8607281 = 8607628
401 + 8607227 = 8607628

Showing the first eight; more decompositions exist.
