Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982638, here are decompositions:

5 + 982633 = 982638
17 + 982621 = 982638
61 + 982577 = 982638
67 + 982571 = 982638
79 + 982559 = 982638
149 + 982489 = 982638
257 + 982381 = 982638
317 + 982321 = 982638

Showing the first eight; more decompositions exist.
