Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726790, here are decompositions:

13 + 8726777 = 8726790
29 + 8726761 = 8726790
31 + 8726759 = 8726790
53 + 8726737 = 8726790
67 + 8726723 = 8726790
103 + 8726687 = 8726790
113 + 8726677 = 8726790
157 + 8726633 = 8726790

Showing the first eight; more decompositions exist.
