Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998654, here are decompositions:

3 + 998651 = 998654
31 + 998623 = 998654
37 + 998617 = 998654
103 + 998551 = 998654
127 + 998527 = 998654
157 + 998497 = 998654
211 + 998443 = 998654
277 + 998377 = 998654

Showing the first eight; more decompositions exist.
