Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626626, here are decompositions:

5 + 8626621 = 8626626
13 + 8626613 = 8626626
23 + 8626603 = 8626626
97 + 8626529 = 8626626
109 + 8626517 = 8626626
139 + 8626487 = 8626626
157 + 8626469 = 8626626
167 + 8626459 = 8626626

Showing the first eight; more decompositions exist.
