Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998726, here are decompositions:

37 + 998689 = 998726
73 + 998653 = 998726
97 + 998629 = 998726
103 + 998623 = 998726
109 + 998617 = 998726
199 + 998527 = 998726
229 + 998497 = 998726
283 + 998443 = 998726

Showing the first eight; more decompositions exist.
