Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725272, here are decompositions:

19 + 8725253 = 8725272
29 + 8725243 = 8725272
53 + 8725219 = 8725272
89 + 8725183 = 8725272
113 + 8725159 = 8725272
131 + 8725141 = 8725272
139 + 8725133 = 8725272
173 + 8725099 = 8725272

Showing the first eight; more decompositions exist.
