Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613578, here are decompositions:

7 + 8613571 = 8613578
19 + 8613559 = 8613578
31 + 8613547 = 8613578
97 + 8613481 = 8613578
139 + 8613439 = 8613578
151 + 8613427 = 8613578
157 + 8613421 = 8613578
199 + 8613379 = 8613578

Showing the first eight; more decompositions exist.
