Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988788, here are decompositions:

5 + 988783 = 988788
29 + 988759 = 988788
61 + 988727 = 988788
107 + 988681 = 988788
127 + 988661 = 988788
137 + 988651 = 988788
139 + 988649 = 988788
181 + 988607 = 988788

Showing the first eight; more decompositions exist.
