Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626624, here are decompositions:

3 + 8626621 = 8626624
11 + 8626613 = 8626624
47 + 8626577 = 8626624
107 + 8626517 = 8626624
131 + 8626493 = 8626624
137 + 8626487 = 8626624
233 + 8626391 = 8626624
353 + 8626271 = 8626624

Showing the first eight; more decompositions exist.
