Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647608, here are decompositions:

19 + 8647589 = 8647608
29 + 8647579 = 8647608
41 + 8647567 = 8647608
71 + 8647537 = 8647608
97 + 8647511 = 8647608
107 + 8647501 = 8647608
139 + 8647469 = 8647608
149 + 8647459 = 8647608

Showing the first eight; more decompositions exist.
