Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725306, here are decompositions:

53 + 8725253 = 8725306
89 + 8725217 = 8725306
167 + 8725139 = 8725306
173 + 8725133 = 8725306
269 + 8725037 = 8725306
479 + 8724827 = 8725306
503 + 8724803 = 8725306
587 + 8724719 = 8725306

Showing the first eight; more decompositions exist.
