Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609472, here are decompositions:

13 + 8609459 = 8609472
23 + 8609449 = 8609472
29 + 8609443 = 8609472
31 + 8609441 = 8609472
41 + 8609431 = 8609472
61 + 8609411 = 8609472
101 + 8609371 = 8609472
139 + 8609333 = 8609472

Showing the first eight; more decompositions exist.
