Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725208, here are decompositions:

31 + 8725177 = 8725208
61 + 8725147 = 8725208
67 + 8725141 = 8725208
97 + 8725111 = 8725208
109 + 8725099 = 8725208
157 + 8725051 = 8725208
241 + 8724967 = 8725208
337 + 8724871 = 8725208

Showing the first eight; more decompositions exist.
