Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982840, here are decompositions:

11 + 982829 = 982840
71 + 982769 = 982840
137 + 982703 = 982840
197 + 982643 = 982840
227 + 982613 = 982840
251 + 982589 = 982840
263 + 982577 = 982840
269 + 982571 = 982840

Showing the first eight; more decompositions exist.
