Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623360, here are decompositions:

17 + 31623343 = 31623360
23 + 31623337 = 31623360
103 + 31623257 = 31623360
137 + 31623223 = 31623360
149 + 31623211 = 31623360
151 + 31623209 = 31623360
179 + 31623181 = 31623360
191 + 31623169 = 31623360

Showing the first eight; more decompositions exist.
