Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988442, here are decompositions:

3 + 988439 = 988442
163 + 988279 = 988442
199 + 988243 = 988442
211 + 988231 = 988442
223 + 988219 = 988442
229 + 988213 = 988442
313 + 988129 = 988442
331 + 988111 = 988442

Showing the first eight; more decompositions exist.
