Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988250, here are decompositions:

7 + 988243 = 988250
13 + 988237 = 988250
19 + 988231 = 988250
31 + 988219 = 988250
37 + 988213 = 988250
103 + 988147 = 988250
139 + 988111 = 988250
157 + 988093 = 988250

Showing the first eight; more decompositions exist.
