Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725286, here are decompositions:

7 + 8725279 = 8725286
43 + 8725243 = 8725286
67 + 8725219 = 8725286
79 + 8725207 = 8725286
103 + 8725183 = 8725286
109 + 8725177 = 8725286
127 + 8725159 = 8725286
139 + 8725147 = 8725286

Showing the first eight; more decompositions exist.
