Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8652840, here are decompositions:

13 + 8652827 = 8652840
17 + 8652823 = 8652840
19 + 8652821 = 8652840
37 + 8652803 = 8652840
43 + 8652797 = 8652840
47 + 8652793 = 8652840
59 + 8652781 = 8652840
67 + 8652773 = 8652840

Showing the first eight; more decompositions exist.
