Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982728, here are decompositions:

31 + 982697 = 982728
41 + 982687 = 982728
107 + 982621 = 982728
139 + 982589 = 982728
151 + 982577 = 982728
157 + 982571 = 982728
239 + 982489 = 982728
347 + 982381 = 982728

Showing the first eight; more decompositions exist.
