Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689880, here are decompositions:

37 + 8689843 = 8689880
103 + 8689777 = 8689880
127 + 8689753 = 8689880
151 + 8689729 = 8689880
193 + 8689687 = 8689880
223 + 8689657 = 8689880
271 + 8689609 = 8689880
307 + 8689573 = 8689880

Showing the first eight; more decompositions exist.
