Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646632, here are decompositions:

61 + 8646571 = 8646632
73 + 8646559 = 8646632
103 + 8646529 = 8646632
229 + 8646403 = 8646632
271 + 8646361 = 8646632
373 + 8646259 = 8646632
409 + 8646223 = 8646632
571 + 8646061 = 8646632

Showing the first eight; more decompositions exist.
