Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690556, here are decompositions:

5 + 8690551 = 8690556
67 + 8690489 = 8690556
79 + 8690477 = 8690556
103 + 8690453 = 8690556
157 + 8690399 = 8690556
179 + 8690377 = 8690556
197 + 8690359 = 8690556
223 + 8690333 = 8690556

Showing the first eight; more decompositions exist.
