Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988938, here are decompositions:

29 + 988909 = 988938
37 + 988901 = 988938
61 + 988877 = 988938
79 + 988859 = 988938
89 + 988849 = 988938
101 + 988837 = 988938
109 + 988829 = 988938
149 + 988789 = 988938

Showing the first eight; more decompositions exist.
