Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998216, here are decompositions:

3 + 998213 = 998216
19 + 998197 = 998216
139 + 998077 = 998216
199 + 998017 = 998216
283 + 997933 = 998216
337 + 997879 = 998216
409 + 997807 = 998216
433 + 997783 = 998216

Showing the first eight; more decompositions exist.
