Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670662, here are decompositions:

43 + 8670619 = 8670662
73 + 8670589 = 8670662
79 + 8670583 = 8670662
103 + 8670559 = 8670662
109 + 8670553 = 8670662
139 + 8670523 = 8670662
163 + 8670499 = 8670662
181 + 8670481 = 8670662

Showing the first eight; more decompositions exist.
