Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720826, here are decompositions:

7 + 8720819 = 8720826
17 + 8720809 = 8720826
19 + 8720807 = 8720826
29 + 8720797 = 8720826
43 + 8720783 = 8720826
53 + 8720773 = 8720826
97 + 8720729 = 8720826
113 + 8720713 = 8720826

Showing the first eight; more decompositions exist.
