Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646260, here are decompositions:

3 + 8646257 = 8646260
13 + 8646247 = 8646260
37 + 8646223 = 8646260
79 + 8646181 = 8646260
97 + 8646163 = 8646260
157 + 8646103 = 8646260
199 + 8646061 = 8646260
373 + 8645887 = 8646260

Showing the first eight; more decompositions exist.
