Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725130, here are decompositions:

19 + 8725111 = 8725130
31 + 8725099 = 8725130
79 + 8725051 = 8725130
109 + 8725021 = 8725130
163 + 8724967 = 8725130
181 + 8724949 = 8725130
283 + 8724847 = 8725130
331 + 8724799 = 8725130

Showing the first eight; more decompositions exist.
