Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609842, here are decompositions:

23 + 8609819 = 8609842
29 + 8609813 = 8609842
89 + 8609753 = 8609842
113 + 8609729 = 8609842
173 + 8609669 = 8609842
179 + 8609663 = 8609842
191 + 8609651 = 8609842
233 + 8609609 = 8609842

Showing the first eight; more decompositions exist.
