Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720994, here are decompositions:

17 + 8720977 = 8720994
41 + 8720953 = 8720994
47 + 8720947 = 8720994
53 + 8720941 = 8720994
83 + 8720911 = 8720994
103 + 8720891 = 8720994
157 + 8720837 = 8720994
197 + 8720797 = 8720994

Showing the first eight; more decompositions exist.
