Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725236, here are decompositions:

17 + 8725219 = 8725236
19 + 8725217 = 8725236
29 + 8725207 = 8725236
53 + 8725183 = 8725236
59 + 8725177 = 8725236
83 + 8725153 = 8725236
89 + 8725147 = 8725236
97 + 8725139 = 8725236

Showing the first eight; more decompositions exist.
