Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725338, here are decompositions:

19 + 8725319 = 8725338
31 + 8725307 = 8725338
59 + 8725279 = 8725338
131 + 8725207 = 8725338
179 + 8725159 = 8725338
191 + 8725147 = 8725338
197 + 8725141 = 8725338
199 + 8725139 = 8725338

Showing the first eight; more decompositions exist.
