Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986828, here are decompositions:

61 + 986767 = 986828
79 + 986749 = 986828
109 + 986719 = 986828
211 + 986617 = 986828
229 + 986599 = 986828
331 + 986497 = 986828
541 + 986287 = 986828
547 + 986281 = 986828

Showing the first eight; more decompositions exist.
