Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725386, here are decompositions:

23 + 8725363 = 8725386
29 + 8725357 = 8725386
67 + 8725319 = 8725386
79 + 8725307 = 8725386
107 + 8725279 = 8725386
167 + 8725219 = 8725386
179 + 8725207 = 8725386
227 + 8725159 = 8725386

Showing the first eight; more decompositions exist.
