Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998386, here are decompositions:

5 + 998381 = 998386
113 + 998273 = 998386
149 + 998237 = 998386
167 + 998219 = 998386
173 + 998213 = 998386
239 + 998147 = 998386
269 + 998117 = 998386
317 + 998069 = 998386

Showing the first eight; more decompositions exist.
