Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988506, here are decompositions:

5 + 988501 = 988506
17 + 988489 = 988506
23 + 988483 = 988506
47 + 988459 = 988506
53 + 988453 = 988506
67 + 988439 = 988506
89 + 988417 = 988506
97 + 988409 = 988506

Showing the first eight; more decompositions exist.
