Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686042, here are decompositions:

41 + 8686001 = 8686042
89 + 8685953 = 8686042
149 + 8685893 = 8686042
179 + 8685863 = 8686042
251 + 8685791 = 8686042
293 + 8685749 = 8686042
311 + 8685731 = 8686042
359 + 8685683 = 8686042

Showing the first eight; more decompositions exist.
