Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988154, here are decompositions:

7 + 988147 = 988154
43 + 988111 = 988154
61 + 988093 = 988154
103 + 988051 = 988154
157 + 987997 = 988154
163 + 987991 = 988154
241 + 987913 = 988154
457 + 987697 = 988154

Showing the first eight; more decompositions exist.
