Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725318, here are decompositions:

11 + 8725307 = 8725318
101 + 8725217 = 8725318
179 + 8725139 = 8725318
227 + 8725091 = 8725318
281 + 8725037 = 8725318
389 + 8724929 = 8725318
491 + 8724827 = 8725318
599 + 8724719 = 8725318

Showing the first eight; more decompositions exist.
