Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725340, here are decompositions:

61 + 8725279 = 8725340
97 + 8725243 = 8725340
157 + 8725183 = 8725340
163 + 8725177 = 8725340
181 + 8725159 = 8725340
193 + 8725147 = 8725340
199 + 8725141 = 8725340
229 + 8725111 = 8725340

Showing the first eight; more decompositions exist.
