Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688684, here are decompositions:

13 + 8688671 = 8688684
71 + 8688613 = 8688684
73 + 8688611 = 8688684
83 + 8688601 = 8688684
101 + 8688583 = 8688684
107 + 8688577 = 8688684
113 + 8688571 = 8688684
127 + 8688557 = 8688684

Showing the first eight; more decompositions exist.
