Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621588, here are decompositions:

7 + 8621581 = 8621588
37 + 8621551 = 8621588
97 + 8621491 = 8621588
109 + 8621479 = 8621588
211 + 8621377 = 8621588
307 + 8621281 = 8621588
379 + 8621209 = 8621588
487 + 8621101 = 8621588

Showing the first eight; more decompositions exist.
