Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725126, here are decompositions:

23 + 8725103 = 8725126
89 + 8725037 = 8725126
197 + 8724929 = 8725126
647 + 8724479 = 8725126
659 + 8724467 = 8725126
797 + 8724329 = 8725126
857 + 8724269 = 8725126
863 + 8724263 = 8725126

Showing the first eight; more decompositions exist.
