Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646938, here are decompositions:

229 + 8646709 = 8646938
271 + 8646667 = 8646938
331 + 8646607 = 8646938
367 + 8646571 = 8646938
379 + 8646559 = 8646938
409 + 8646529 = 8646938
577 + 8646361 = 8646938
661 + 8646277 = 8646938

Showing the first eight; more decompositions exist.
