Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980398, here are decompositions:

5 + 980393 = 980398
71 + 980327 = 980398
137 + 980261 = 980398
149 + 980249 = 980398
179 + 980219 = 980398
239 + 980159 = 980398
281 + 980117 = 980398
317 + 980081 = 980398

Showing the first eight; more decompositions exist.
