Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684820, here are decompositions:

31 + 8684789 = 8684820
37 + 8684783 = 8684820
59 + 8684761 = 8684820
61 + 8684759 = 8684820
73 + 8684747 = 8684820
107 + 8684713 = 8684820
127 + 8684693 = 8684820
163 + 8684657 = 8684820

Showing the first eight; more decompositions exist.
