Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679938, here are decompositions:

67 + 8679871 = 8679938
97 + 8679841 = 8679938
199 + 8679739 = 8679938
229 + 8679709 = 8679938
331 + 8679607 = 8679938
409 + 8679529 = 8679938
439 + 8679499 = 8679938
541 + 8679397 = 8679938

Showing the first eight; more decompositions exist.
