Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642922, here are decompositions:

11 + 8642911 = 8642922
19 + 8642903 = 8642922
59 + 8642863 = 8642922
61 + 8642861 = 8642922
73 + 8642849 = 8642922
83 + 8642839 = 8642922
103 + 8642819 = 8642922
149 + 8642773 = 8642922

Showing the first eight; more decompositions exist.
