Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982780, here are decompositions:

3 + 982777 = 982780
11 + 982769 = 982780
83 + 982697 = 982780
137 + 982643 = 982780
167 + 982613 = 982780
191 + 982589 = 982780
443 + 982337 = 982780
479 + 982301 = 982780

Showing the first eight; more decompositions exist.
