Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725436, here are decompositions:

7 + 8725429 = 8725436
37 + 8725399 = 8725436
73 + 8725363 = 8725436
79 + 8725357 = 8725436
157 + 8725279 = 8725436
193 + 8725243 = 8725436
229 + 8725207 = 8725436
277 + 8725159 = 8725436

Showing the first eight; more decompositions exist.
