Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716640, here are decompositions:

13 + 8716627 = 8716640
61 + 8716579 = 8716640
73 + 8716567 = 8716640
109 + 8716531 = 8716640
151 + 8716489 = 8716640
193 + 8716447 = 8716640
199 + 8716441 = 8716640
211 + 8716429 = 8716640

Showing the first eight; more decompositions exist.
