Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643434, here are decompositions:

67 + 8643367 = 8643434
97 + 8643337 = 8643434
127 + 8643307 = 8643434
211 + 8643223 = 8643434
223 + 8643211 = 8643434
313 + 8643121 = 8643434
421 + 8643013 = 8643434
487 + 8642947 = 8643434

Showing the first eight; more decompositions exist.
