Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679478, here are decompositions:

29 + 8679449 = 8679478
131 + 8679347 = 8679478
167 + 8679311 = 8679478
257 + 8679221 = 8679478
419 + 8679059 = 8679478
701 + 8678777 = 8679478
719 + 8678759 = 8679478
809 + 8678669 = 8679478

Showing the first eight; more decompositions exist.
