Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679142, here are decompositions:

5 + 8679137 = 8679142
71 + 8679071 = 8679142
83 + 8679059 = 8679142
179 + 8678963 = 8679142
191 + 8678951 = 8679142
239 + 8678903 = 8679142
359 + 8678783 = 8679142
383 + 8678759 = 8679142

Showing the first eight; more decompositions exist.
