Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626556, here are decompositions:

7 + 8626549 = 8626556
97 + 8626459 = 8626556
139 + 8626417 = 8626556
307 + 8626249 = 8626556
313 + 8626243 = 8626556
397 + 8626159 = 8626556
457 + 8626099 = 8626556
577 + 8625979 = 8626556

Showing the first eight; more decompositions exist.
