Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982778, here are decompositions:

19 + 982759 = 982778
37 + 982741 = 982778
157 + 982621 = 982778
397 + 982381 = 982778
439 + 982339 = 982778
457 + 982321 = 982778
547 + 982231 = 982778
607 + 982171 = 982778

Showing the first eight; more decompositions exist.
