Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998906, here are decompositions:

67 + 998839 = 998906
127 + 998779 = 998906
157 + 998749 = 998906
163 + 998743 = 998906
277 + 998629 = 998906
283 + 998623 = 998906
367 + 998539 = 998906
379 + 998527 = 998906

Showing the first eight; more decompositions exist.
