Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988970, here are decompositions:

7 + 988963 = 988970
19 + 988951 = 988970
61 + 988909 = 988970
109 + 988861 = 988970
181 + 988789 = 988970
211 + 988759 = 988970
277 + 988693 = 988970
379 + 988591 = 988970

Showing the first eight; more decompositions exist.
