Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643954, here are decompositions:

13 + 8643941 = 8643954
31 + 8643923 = 8643954
61 + 8643893 = 8643954
103 + 8643851 = 8643954
157 + 8643797 = 8643954
167 + 8643787 = 8643954
197 + 8643757 = 8643954
233 + 8643721 = 8643954

Showing the first eight; more decompositions exist.
