Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988406, here are decompositions:

109 + 988297 = 988406
127 + 988279 = 988406
163 + 988243 = 988406
193 + 988213 = 988406
277 + 988129 = 988406
313 + 988093 = 988406
337 + 988069 = 988406
373 + 988033 = 988406

Showing the first eight; more decompositions exist.
