Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715806, here are decompositions:

13 + 8715793 = 8715806
19 + 8715787 = 8715806
37 + 8715769 = 8715806
97 + 8715709 = 8715806
103 + 8715703 = 8715806
109 + 8715697 = 8715806
139 + 8715667 = 8715806
157 + 8715649 = 8715806

Showing the first eight; more decompositions exist.
