Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626420, here are decompositions:

3 + 8626417 = 8626420
29 + 8626391 = 8626420
71 + 8626349 = 8626420
137 + 8626283 = 8626420
149 + 8626271 = 8626420
191 + 8626229 = 8626420
239 + 8626181 = 8626420
251 + 8626169 = 8626420

Showing the first eight; more decompositions exist.
