Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626426, here are decompositions:

5 + 8626421 = 8626426
197 + 8626229 = 8626426
257 + 8626169 = 8626426
317 + 8626109 = 8626426
359 + 8626067 = 8626426
383 + 8626043 = 8626426
443 + 8625983 = 8626426
467 + 8625959 = 8626426

Showing the first eight; more decompositions exist.
