Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998290, here are decompositions:

3 + 998287 = 998290
17 + 998273 = 998290
47 + 998243 = 998290
53 + 998237 = 998290
71 + 998219 = 998290
89 + 998201 = 998290
173 + 998117 = 998290
179 + 998111 = 998290

Showing the first eight; more decompositions exist.
