Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670740, here are decompositions:

31 + 8670709 = 8670740
37 + 8670703 = 8670740
61 + 8670679 = 8670740
73 + 8670667 = 8670740
103 + 8670637 = 8670740
151 + 8670589 = 8670740
157 + 8670583 = 8670740
181 + 8670559 = 8670740

Showing the first eight; more decompositions exist.
