Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998822, here are decompositions:

3 + 998819 = 998822
43 + 998779 = 998822
73 + 998749 = 998822
79 + 998743 = 998822
193 + 998629 = 998822
199 + 998623 = 998822
271 + 998551 = 998822
283 + 998539 = 998822

Showing the first eight; more decompositions exist.
