Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637080, here are decompositions:

13 + 8637067 = 8637080
19 + 8637061 = 8637080
73 + 8637007 = 8637080
157 + 8636923 = 8637080
163 + 8636917 = 8637080
181 + 8636899 = 8637080
211 + 8636869 = 8637080
223 + 8636857 = 8637080

Showing the first eight; more decompositions exist.
