Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988166, here are decompositions:

19 + 988147 = 988166
37 + 988129 = 988166
73 + 988093 = 988166
97 + 988069 = 988166
373 + 987793 = 988166
607 + 987559 = 988166
643 + 987523 = 988166
709 + 987457 = 988166

Showing the first eight; more decompositions exist.
