Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000398, here are decompositions:

5 + 1000393 = 1000398
17 + 1000381 = 1000398
31 + 1000367 = 1000398
41 + 1000357 = 1000398
107 + 1000291 = 1000398
109 + 1000289 = 1000398
149 + 1000249 = 1000398
167 + 1000231 = 1000398

Showing the first eight; more decompositions exist.
