Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988436, here are decompositions:

19 + 988417 = 988436
79 + 988357 = 988436
139 + 988297 = 988436
157 + 988279 = 988436
193 + 988243 = 988436
199 + 988237 = 988436
223 + 988213 = 988436
307 + 988129 = 988436

Showing the first eight; more decompositions exist.
