Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626216, here are decompositions:

47 + 8626169 = 8626216
107 + 8626109 = 8626216
113 + 8626103 = 8626216
149 + 8626067 = 8626216
173 + 8626043 = 8626216
233 + 8625983 = 8626216
257 + 8625959 = 8626216
383 + 8625833 = 8626216

Showing the first eight; more decompositions exist.
