Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706686, here are decompositions:

19 + 8706667 = 8706686
73 + 8706613 = 8706686
139 + 8706547 = 8706686
223 + 8706463 = 8706686
229 + 8706457 = 8706686
283 + 8706403 = 8706686
337 + 8706349 = 8706686
349 + 8706337 = 8706686

Showing the first eight; more decompositions exist.
