Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725238, here are decompositions:

19 + 8725219 = 8725238
31 + 8725207 = 8725238
61 + 8725177 = 8725238
79 + 8725159 = 8725238
97 + 8725141 = 8725238
127 + 8725111 = 8725238
139 + 8725099 = 8725238
199 + 8725039 = 8725238

Showing the first eight; more decompositions exist.
