Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647620, here are decompositions:

31 + 8647589 = 8647620
41 + 8647579 = 8647620
53 + 8647567 = 8647620
83 + 8647537 = 8647620
89 + 8647531 = 8647620
109 + 8647511 = 8647620
151 + 8647469 = 8647620
173 + 8647447 = 8647620

Showing the first eight; more decompositions exist.
