Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725724, here are decompositions:

43 + 8725681 = 8725724
67 + 8725657 = 8725724
97 + 8725627 = 8725724
103 + 8725621 = 8725724
157 + 8725567 = 8725724
193 + 8725531 = 8725724
367 + 8725357 = 8725724
541 + 8725183 = 8725724

Showing the first eight; more decompositions exist.
