Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621756, here are decompositions:

7 + 8621749 = 8621756
79 + 8621677 = 8621756
103 + 8621653 = 8621756
139 + 8621617 = 8621756
277 + 8621479 = 8621756
313 + 8621443 = 8621756
379 + 8621377 = 8621756
457 + 8621299 = 8621756

Showing the first eight; more decompositions exist.
