Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621758, here are decompositions:

11 + 8621747 = 8621758
149 + 8621609 = 8621758
281 + 8621477 = 8621758
347 + 8621411 = 8621758
419 + 8621339 = 8621758
449 + 8621309 = 8621758
521 + 8621237 = 8621758
557 + 8621201 = 8621758

Showing the first eight; more decompositions exist.
