Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725160, here are decompositions:

7 + 8725153 = 8725160
13 + 8725147 = 8725160
19 + 8725141 = 8725160
61 + 8725099 = 8725160
109 + 8725051 = 8725160
139 + 8725021 = 8725160
193 + 8724967 = 8725160
211 + 8724949 = 8725160

Showing the first eight; more decompositions exist.
