Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616490, here are decompositions:

59 + 8616431 = 8616490
83 + 8616407 = 8616490
137 + 8616353 = 8616490
167 + 8616323 = 8616490
191 + 8616299 = 8616490
269 + 8616221 = 8616490
293 + 8616197 = 8616490
317 + 8616173 = 8616490

Showing the first eight; more decompositions exist.
