Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644588, here are decompositions:

59 + 8644529 = 8644588
89 + 8644499 = 8644588
131 + 8644457 = 8644588
137 + 8644451 = 8644588
149 + 8644439 = 8644588
191 + 8644397 = 8644588
257 + 8644331 = 8644588
401 + 8644187 = 8644588

Showing the first eight; more decompositions exist.
