Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998318, here are decompositions:

7 + 998311 = 998318
31 + 998287 = 998318
37 + 998281 = 998318
151 + 998167 = 998318
157 + 998161 = 998318
241 + 998077 = 998318
421 + 997897 = 998318
439 + 997879 = 998318

Showing the first eight; more decompositions exist.
