Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655266, here are decompositions:

3 + 8655263 = 8655266
7 + 8655259 = 8655266
163 + 8655103 = 8655266
229 + 8655037 = 8655266
307 + 8654959 = 8655266
349 + 8654917 = 8655266
457 + 8654809 = 8655266
463 + 8654803 = 8655266

Showing the first eight; more decompositions exist.
