Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616520, here are decompositions:

89 + 8616431 = 8616520
113 + 8616407 = 8616520
149 + 8616371 = 8616520
167 + 8616353 = 8616520
197 + 8616323 = 8616520
239 + 8616281 = 8616520
317 + 8616203 = 8616520
347 + 8616173 = 8616520

Showing the first eight; more decompositions exist.
