Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998630, here are decompositions:

7 + 998623 = 998630
13 + 998617 = 998630
79 + 998551 = 998630
103 + 998527 = 998630
211 + 998419 = 998630
277 + 998353 = 998630
349 + 998281 = 998630
433 + 998197 = 998630

Showing the first eight; more decompositions exist.
