Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643484, here are decompositions:

41 + 8643443 = 8643484
167 + 8643317 = 8643484
197 + 8643287 = 8643484
347 + 8643137 = 8643484
401 + 8643083 = 8643484
431 + 8643053 = 8643484
461 + 8643023 = 8643484
557 + 8642927 = 8643484

Showing the first eight; more decompositions exist.
