Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988908, here are decompositions:

7 + 988901 = 988908
31 + 988877 = 988908
47 + 988861 = 988908
59 + 988849 = 988908
71 + 988837 = 988908
79 + 988829 = 988908
149 + 988759 = 988908
181 + 988727 = 988908

Showing the first eight; more decompositions exist.
