Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725178, here are decompositions:

19 + 8725159 = 8725178
31 + 8725147 = 8725178
37 + 8725141 = 8725178
67 + 8725111 = 8725178
79 + 8725099 = 8725178
127 + 8725051 = 8725178
139 + 8725039 = 8725178
157 + 8725021 = 8725178

Showing the first eight; more decompositions exist.
