Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998474, here are decompositions:

3 + 998471 = 998474
31 + 998443 = 998474
97 + 998377 = 998474
163 + 998311 = 998474
193 + 998281 = 998474
277 + 998197 = 998474
307 + 998167 = 998474
313 + 998161 = 998474

Showing the first eight; more decompositions exist.
