Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647532, here are decompositions:

31 + 8647501 = 8647532
73 + 8647459 = 8647532
139 + 8647393 = 8647532
163 + 8647369 = 8647532
349 + 8647183 = 8647532
409 + 8647123 = 8647532
571 + 8646961 = 8647532
643 + 8646889 = 8647532

Showing the first eight; more decompositions exist.
