Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605842, here are decompositions:

13 + 8605829 = 8605842
19 + 8605823 = 8605842
29 + 8605813 = 8605842
31 + 8605811 = 8605842
41 + 8605801 = 8605842
53 + 8605789 = 8605842
109 + 8605733 = 8605842
151 + 8605691 = 8605842

Showing the first eight; more decompositions exist.
