Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998818, here are decompositions:

5 + 998813 = 998818
59 + 998759 = 998818
101 + 998717 = 998818
131 + 998687 = 998818
137 + 998681 = 998818
167 + 998651 = 998818
257 + 998561 = 998818
281 + 998537 = 998818

Showing the first eight; more decompositions exist.
