Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657672, here are decompositions:

43 + 8657629 = 8657672
61 + 8657611 = 8657672
103 + 8657569 = 8657672
109 + 8657563 = 8657672
139 + 8657533 = 8657672
211 + 8657461 = 8657672
223 + 8657449 = 8657672
241 + 8657431 = 8657672

Showing the first eight; more decompositions exist.
