Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998918, here are decompositions:

61 + 998857 = 998918
79 + 998839 = 998918
139 + 998779 = 998918
181 + 998737 = 998918
229 + 998689 = 998918
367 + 998551 = 998918
379 + 998539 = 998918
421 + 998497 = 998918

Showing the first eight; more decompositions exist.
