Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988140, here are decompositions:

11 + 988129 = 988140
29 + 988111 = 988140
31 + 988109 = 988140
47 + 988093 = 988140
71 + 988069 = 988140
73 + 988067 = 988140
79 + 988061 = 988140
89 + 988051 = 988140

Showing the first eight; more decompositions exist.
