Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725148, here are decompositions:

7 + 8725141 = 8725148
37 + 8725111 = 8725148
97 + 8725051 = 8725148
109 + 8725039 = 8725148
127 + 8725021 = 8725148
181 + 8724967 = 8725148
199 + 8724949 = 8725148
277 + 8724871 = 8725148

Showing the first eight; more decompositions exist.
