Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641434, here are decompositions:

5 + 8641429 = 8641434
13 + 8641421 = 8641434
73 + 8641361 = 8641434
83 + 8641351 = 8641434
103 + 8641331 = 8641434
107 + 8641327 = 8641434
223 + 8641211 = 8641434
337 + 8641097 = 8641434

Showing the first eight; more decompositions exist.
