Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726820, here are decompositions:

17 + 8726803 = 8726820
19 + 8726801 = 8726820
31 + 8726789 = 8726820
43 + 8726777 = 8726820
59 + 8726761 = 8726820
61 + 8726759 = 8726820
83 + 8726737 = 8726820
97 + 8726723 = 8726820

Showing the first eight; more decompositions exist.
