Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634628, here are decompositions:

11 + 8634617 = 8634628
47 + 8634581 = 8634628
71 + 8634557 = 8634628
89 + 8634539 = 8634628
131 + 8634497 = 8634628
179 + 8634449 = 8634628
257 + 8634371 = 8634628
269 + 8634359 = 8634628

Showing the first eight; more decompositions exist.
