Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982816, here are decompositions:

47 + 982769 = 982816
113 + 982703 = 982816
173 + 982643 = 982816
227 + 982589 = 982816
239 + 982577 = 982816
257 + 982559 = 982816
479 + 982337 = 982816
599 + 982217 = 982816

Showing the first eight; more decompositions exist.
