Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688648, here are decompositions:

19 + 8688629 = 8688648
37 + 8688611 = 8688648
41 + 8688607 = 8688648
47 + 8688601 = 8688648
71 + 8688577 = 8688648
79 + 8688569 = 8688648
97 + 8688551 = 8688648
127 + 8688521 = 8688648

Showing the first eight; more decompositions exist.
