Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670620, here are decompositions:

31 + 8670589 = 8670620
37 + 8670583 = 8670620
61 + 8670559 = 8670620
67 + 8670553 = 8670620
97 + 8670523 = 8670620
139 + 8670481 = 8670620
223 + 8670397 = 8670620
307 + 8670313 = 8670620

Showing the first eight; more decompositions exist.
