Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626290, here are decompositions:

7 + 8626283 = 8626290
19 + 8626271 = 8626290
41 + 8626249 = 8626290
47 + 8626243 = 8626290
53 + 8626237 = 8626290
61 + 8626229 = 8626290
109 + 8626181 = 8626290
131 + 8626159 = 8626290

Showing the first eight; more decompositions exist.
