Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688738, here are decompositions:

31 + 8688707 = 8688738
41 + 8688697 = 8688738
67 + 8688671 = 8688738
109 + 8688629 = 8688738
127 + 8688611 = 8688738
131 + 8688607 = 8688738
137 + 8688601 = 8688738
167 + 8688571 = 8688738

Showing the first eight; more decompositions exist.
