Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672556, here are decompositions:

5 + 8672551 = 8672556
17 + 8672539 = 8672556
29 + 8672527 = 8672556
37 + 8672519 = 8672556
43 + 8672513 = 8672556
47 + 8672509 = 8672556
73 + 8672483 = 8672556
127 + 8672429 = 8672556

Showing the first eight; more decompositions exist.
