Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718578, here are decompositions:

7 + 8718571 = 8718578
109 + 8718469 = 8718578
139 + 8718439 = 8718578
151 + 8718427 = 8718578
229 + 8718349 = 8718578
277 + 8718301 = 8718578
307 + 8718271 = 8718578
331 + 8718247 = 8718578

Showing the first eight; more decompositions exist.
