Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655080, here are decompositions:

43 + 8655037 = 8655080
73 + 8655007 = 8655080
139 + 8654941 = 8655080
163 + 8654917 = 8655080
241 + 8654839 = 8655080
271 + 8654809 = 8655080
277 + 8654803 = 8655080
307 + 8654773 = 8655080

Showing the first eight; more decompositions exist.
