Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642536, here are decompositions:

3 + 8642533 = 8642536
17 + 8642519 = 8642536
29 + 8642507 = 8642536
47 + 8642489 = 8642536
83 + 8642453 = 8642536
107 + 8642429 = 8642536
233 + 8642303 = 8642536
347 + 8642189 = 8642536

Showing the first eight; more decompositions exist.
