Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998554, here are decompositions:

3 + 998551 = 998554
17 + 998537 = 998554
41 + 998513 = 998554
83 + 998471 = 998554
131 + 998423 = 998554
173 + 998381 = 998554
281 + 998273 = 998554
311 + 998243 = 998554

Showing the first eight; more decompositions exist.
