Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643162, here are decompositions:

13 + 8643149 = 8643162
19 + 8643143 = 8643162
29 + 8643133 = 8643162
41 + 8643121 = 8643162
53 + 8643109 = 8643162
71 + 8643091 = 8643162
79 + 8643083 = 8643162
103 + 8643059 = 8643162

Showing the first eight; more decompositions exist.
