Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988340, here are decompositions:

19 + 988321 = 988340
43 + 988297 = 988340
61 + 988279 = 988340
97 + 988243 = 988340
103 + 988237 = 988340
109 + 988231 = 988340
127 + 988213 = 988340
193 + 988147 = 988340

Showing the first eight; more decompositions exist.
