Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670782, here are decompositions:

31 + 8670751 = 8670782
73 + 8670709 = 8670782
79 + 8670703 = 8670782
103 + 8670679 = 8670782
163 + 8670619 = 8670782
193 + 8670589 = 8670782
199 + 8670583 = 8670782
223 + 8670559 = 8670782

Showing the first eight; more decompositions exist.
