Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605156, here are decompositions:

3 + 8605153 = 8605156
137 + 8605019 = 8605156
173 + 8604983 = 8605156
179 + 8604977 = 8605156
293 + 8604863 = 8605156
347 + 8604809 = 8605156
359 + 8604797 = 8605156
389 + 8604767 = 8605156

Showing the first eight; more decompositions exist.
