Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725184, here are decompositions:

7 + 8725177 = 8725184
31 + 8725153 = 8725184
37 + 8725147 = 8725184
43 + 8725141 = 8725184
73 + 8725111 = 8725184
163 + 8725021 = 8725184
241 + 8724943 = 8725184
313 + 8724871 = 8725184

Showing the first eight; more decompositions exist.
