Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998786, here are decompositions:

7 + 998779 = 998786
37 + 998749 = 998786
43 + 998743 = 998786
97 + 998689 = 998786
157 + 998629 = 998786
163 + 998623 = 998786
367 + 998419 = 998786
409 + 998377 = 998786

Showing the first eight; more decompositions exist.
