Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684028, here are decompositions:

5 + 8684023 = 8684028
19 + 8684009 = 8684028
131 + 8683897 = 8684028
151 + 8683877 = 8684028
271 + 8683757 = 8684028
337 + 8683691 = 8684028
347 + 8683681 = 8684028
389 + 8683639 = 8684028

Showing the first eight; more decompositions exist.
