Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988556, here are decompositions:

7 + 988549 = 988556
67 + 988489 = 988556
73 + 988483 = 988556
97 + 988459 = 988556
103 + 988453 = 988556
139 + 988417 = 988556
199 + 988357 = 988556
277 + 988279 = 988556

Showing the first eight; more decompositions exist.
