Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688838, here are decompositions:

29 + 8688809 = 8688838
47 + 8688791 = 8688838
131 + 8688707 = 8688838
167 + 8688671 = 8688838
227 + 8688611 = 8688838
269 + 8688569 = 8688838
281 + 8688557 = 8688838
311 + 8688527 = 8688838

Showing the first eight; more decompositions exist.
