Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684138, here are decompositions:

7 + 8684131 = 8684138
31 + 8684107 = 8684138
61 + 8684077 = 8684138
109 + 8684029 = 8684138
241 + 8683897 = 8684138
409 + 8683729 = 8684138
439 + 8683699 = 8684138
457 + 8683681 = 8684138

Showing the first eight; more decompositions exist.
