Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621488, here are decompositions:

11 + 8621477 = 8621488
59 + 8621429 = 8621488
149 + 8621339 = 8621488
179 + 8621309 = 8621488
251 + 8621237 = 8621488
401 + 8621087 = 8621488
479 + 8621009 = 8621488
641 + 8620847 = 8621488

Showing the first eight; more decompositions exist.
