Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988566, here are decompositions:

17 + 988549 = 988566
83 + 988483 = 988566
107 + 988459 = 988566
113 + 988453 = 988566
127 + 988439 = 988566
149 + 988417 = 988566
157 + 988409 = 988566
199 + 988367 = 988566

Showing the first eight; more decompositions exist.
