Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617578, here are decompositions:

17 + 8617561 = 8617578
29 + 8617549 = 8617578
31 + 8617547 = 8617578
59 + 8617519 = 8617578
131 + 8617447 = 8617578
139 + 8617439 = 8617578
181 + 8617397 = 8617578
197 + 8617381 = 8617578

Showing the first eight; more decompositions exist.
