Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998774, here are decompositions:

31 + 998743 = 998774
37 + 998737 = 998774
151 + 998623 = 998774
157 + 998617 = 998774
223 + 998551 = 998774
277 + 998497 = 998774
331 + 998443 = 998774
397 + 998377 = 998774

Showing the first eight; more decompositions exist.
