Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998358, here are decompositions:

5 + 998353 = 998358
29 + 998329 = 998358
47 + 998311 = 998358
71 + 998287 = 998358
139 + 998219 = 998358
157 + 998201 = 998358
191 + 998167 = 998358
197 + 998161 = 998358

Showing the first eight; more decompositions exist.
