Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681246, here are decompositions:

3 + 8681243 = 8681246
157 + 8681089 = 8681246
199 + 8681047 = 8681246
307 + 8680939 = 8681246
337 + 8680909 = 8681246
433 + 8680813 = 8681246
523 + 8680723 = 8681246
547 + 8680699 = 8681246

Showing the first eight; more decompositions exist.
