Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690820, here are decompositions:

7 + 8690813 = 8690820
23 + 8690797 = 8690820
31 + 8690789 = 8690820
37 + 8690783 = 8690820
53 + 8690767 = 8690820
79 + 8690741 = 8690820
107 + 8690713 = 8690820
137 + 8690683 = 8690820

Showing the first eight; more decompositions exist.
