Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998772, here are decompositions:

13 + 998759 = 998772
23 + 998749 = 998772
29 + 998743 = 998772
83 + 998689 = 998772
139 + 998633 = 998772
149 + 998623 = 998772
211 + 998561 = 998772
233 + 998539 = 998772

Showing the first eight; more decompositions exist.
