Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998528, here are decompositions:

31 + 998497 = 998528
109 + 998419 = 998528
151 + 998377 = 998528
199 + 998329 = 998528
241 + 998287 = 998528
331 + 998197 = 998528
367 + 998161 = 998528
457 + 998071 = 998528

Showing the first eight; more decompositions exist.
