Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643156, here are decompositions:

7 + 8643149 = 8643156
13 + 8643143 = 8643156
19 + 8643137 = 8643156
23 + 8643133 = 8643156
47 + 8643109 = 8643156
73 + 8643083 = 8643156
79 + 8643077 = 8643156
97 + 8643059 = 8643156

Showing the first eight; more decompositions exist.
