Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8652642, here are decompositions:

13 + 8652629 = 8652642
29 + 8652613 = 8652642
41 + 8652601 = 8652642
71 + 8652571 = 8652642
79 + 8652563 = 8652642
149 + 8652493 = 8652642
181 + 8652461 = 8652642
211 + 8652431 = 8652642

Showing the first eight; more decompositions exist.
