Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621776, here are decompositions:

3 + 8621773 = 8621776
29 + 8621747 = 8621776
83 + 8621693 = 8621776
167 + 8621609 = 8621776
347 + 8621429 = 8621776
467 + 8621309 = 8621776
563 + 8621213 = 8621776
587 + 8621189 = 8621776

Showing the first eight; more decompositions exist.
