Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998380, here are decompositions:

3 + 998377 = 998380
107 + 998273 = 998380
137 + 998243 = 998380
167 + 998213 = 998380
179 + 998201 = 998380
233 + 998147 = 998380
263 + 998117 = 998380
269 + 998111 = 998380

Showing the first eight; more decompositions exist.
