Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646434, here are decompositions:

31 + 8646403 = 8646434
73 + 8646361 = 8646434
157 + 8646277 = 8646434
211 + 8646223 = 8646434
271 + 8646163 = 8646434
331 + 8646103 = 8646434
373 + 8646061 = 8646434
463 + 8645971 = 8646434

Showing the first eight; more decompositions exist.
