Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988490, here are decompositions:

7 + 988483 = 988490
31 + 988459 = 988490
37 + 988453 = 988490
73 + 988417 = 988490
193 + 988297 = 988490
211 + 988279 = 988490
271 + 988219 = 988490
277 + 988213 = 988490

Showing the first eight; more decompositions exist.
