Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672624, here are decompositions:

3 + 8672621 = 8672624
61 + 8672563 = 8672624
73 + 8672551 = 8672624
97 + 8672527 = 8672624
271 + 8672353 = 8672624
277 + 8672347 = 8672624
421 + 8672203 = 8672624
463 + 8672161 = 8672624

Showing the first eight; more decompositions exist.
