Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686742, here are decompositions:

13 + 8686729 = 8686742
73 + 8686669 = 8686742
241 + 8686501 = 8686742
271 + 8686471 = 8686742
283 + 8686459 = 8686742
373 + 8686369 = 8686742
433 + 8686309 = 8686742
601 + 8686141 = 8686742

Showing the first eight; more decompositions exist.
