Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605242, here are decompositions:

5 + 8605237 = 8605242
11 + 8605231 = 8605242
13 + 8605229 = 8605242
31 + 8605211 = 8605242
71 + 8605171 = 8605242
73 + 8605169 = 8605242
83 + 8605159 = 8605242
89 + 8605153 = 8605242

Showing the first eight; more decompositions exist.
