Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725356, here are decompositions:

37 + 8725319 = 8725356
103 + 8725253 = 8725356
113 + 8725243 = 8725356
137 + 8725219 = 8725356
139 + 8725217 = 8725356
149 + 8725207 = 8725356
173 + 8725183 = 8725356
179 + 8725177 = 8725356

Showing the first eight; more decompositions exist.
