Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626228, here are decompositions:

47 + 8626181 = 8626228
59 + 8626169 = 8626228
89 + 8626139 = 8626228
167 + 8626061 = 8626228
227 + 8626001 = 8626228
269 + 8625959 = 8626228
419 + 8625809 = 8626228
521 + 8625707 = 8626228

Showing the first eight; more decompositions exist.
