Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688732, here are decompositions:

29 + 8688703 = 8688732
61 + 8688671 = 8688732
103 + 8688629 = 8688732
131 + 8688601 = 8688732
139 + 8688593 = 8688732
149 + 8688583 = 8688732
163 + 8688569 = 8688732
179 + 8688553 = 8688732

Showing the first eight; more decompositions exist.
