Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672578, here are decompositions:

17 + 8672561 = 8672578
59 + 8672519 = 8672578
107 + 8672471 = 8672578
137 + 8672441 = 8672578
149 + 8672429 = 8672578
191 + 8672387 = 8672578
197 + 8672381 = 8672578
281 + 8672297 = 8672578

Showing the first eight; more decompositions exist.
