Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642956, here are decompositions:

5 + 8642951 = 8642956
17 + 8642939 = 8642956
29 + 8642927 = 8642956
53 + 8642903 = 8642956
59 + 8642897 = 8642956
107 + 8642849 = 8642956
137 + 8642819 = 8642956
233 + 8642723 = 8642956

Showing the first eight; more decompositions exist.
