Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637146, here are decompositions:

13 + 8637133 = 8637146
43 + 8637103 = 8637146
79 + 8637067 = 8637146
139 + 8637007 = 8637146
157 + 8636989 = 8637146
223 + 8636923 = 8637146
229 + 8636917 = 8637146
277 + 8636869 = 8637146

Showing the first eight; more decompositions exist.
