Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689844, here are decompositions:

3 + 8689841 = 8689844
67 + 8689777 = 8689844
157 + 8689687 = 8689844
271 + 8689573 = 8689844
307 + 8689537 = 8689844
523 + 8689321 = 8689844
571 + 8689273 = 8689844
601 + 8689243 = 8689844

Showing the first eight; more decompositions exist.
