Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622636, here are decompositions:

59 + 8622577 = 8622636
73 + 8622563 = 8622636
107 + 8622529 = 8622636
137 + 8622499 = 8622636
149 + 8622487 = 8622636
163 + 8622473 = 8622636
167 + 8622469 = 8622636
173 + 8622463 = 8622636

Showing the first eight; more decompositions exist.
