Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988148, here are decompositions:

19 + 988129 = 988148
37 + 988111 = 988148
79 + 988069 = 988148
97 + 988051 = 988148
127 + 988021 = 988148
151 + 987997 = 988148
157 + 987991 = 988148
409 + 987739 = 988148

Showing the first eight; more decompositions exist.
