Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671250, here are decompositions:

19 + 8671231 = 8671250
31 + 8671219 = 8671250
73 + 8671177 = 8671250
103 + 8671147 = 8671250
151 + 8671099 = 8671250
193 + 8671057 = 8671250
199 + 8671051 = 8671250
241 + 8671009 = 8671250

Showing the first eight; more decompositions exist.
