Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688450, here are decompositions:

13 + 8688437 = 8688450
41 + 8688409 = 8688450
53 + 8688397 = 8688450
97 + 8688353 = 8688450
101 + 8688349 = 8688450
139 + 8688311 = 8688450
151 + 8688299 = 8688450
163 + 8688287 = 8688450

Showing the first eight; more decompositions exist.
