Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679238, here are decompositions:

17 + 8679221 = 8679238
59 + 8679179 = 8679238
101 + 8679137 = 8679238
167 + 8679071 = 8679238
179 + 8679059 = 8679238
311 + 8678927 = 8679238
461 + 8678777 = 8679238
479 + 8678759 = 8679238

Showing the first eight; more decompositions exist.
