Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684180, here are decompositions:

3 + 8684177 = 8684180
7 + 8684173 = 8684180
73 + 8684107 = 8684180
103 + 8684077 = 8684180
151 + 8684029 = 8684180
157 + 8684023 = 8684180
283 + 8683897 = 8684180
397 + 8683783 = 8684180

Showing the first eight; more decompositions exist.
