Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988086, here are decompositions:

17 + 988069 = 988086
19 + 988067 = 988086
53 + 988033 = 988086
79 + 988007 = 988086
89 + 987997 = 988086
103 + 987983 = 988086
107 + 987979 = 988086
157 + 987929 = 988086

Showing the first eight; more decompositions exist.
