Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998622, here are decompositions:

5 + 998617 = 998622
61 + 998561 = 998622
71 + 998551 = 998622
83 + 998539 = 998622
109 + 998513 = 998622
151 + 998471 = 998622
179 + 998443 = 998622
193 + 998429 = 998622

Showing the first eight; more decompositions exist.
