Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681044, here are decompositions:

23 + 8681021 = 8681044
41 + 8681003 = 8681044
137 + 8680907 = 8681044
173 + 8680871 = 8681044
233 + 8680811 = 8681044
263 + 8680781 = 8681044
311 + 8680733 = 8681044
347 + 8680697 = 8681044

Showing the first eight; more decompositions exist.
