Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725308, here are decompositions:

29 + 8725279 = 8725308
89 + 8725219 = 8725308
101 + 8725207 = 8725308
131 + 8725177 = 8725308
149 + 8725159 = 8725308
167 + 8725141 = 8725308
197 + 8725111 = 8725308
257 + 8725051 = 8725308

Showing the first eight; more decompositions exist.
