Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606578, here are decompositions:

41 + 8606537 = 8606578
131 + 8606447 = 8606578
137 + 8606441 = 8606578
191 + 8606387 = 8606578
251 + 8606327 = 8606578
269 + 8606309 = 8606578
317 + 8606261 = 8606578
359 + 8606219 = 8606578

Showing the first eight; more decompositions exist.
