Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681080, here are decompositions:

3 + 8681077 = 8681080
59 + 8681021 = 8681080
71 + 8681009 = 8681080
173 + 8680907 = 8681080
179 + 8680901 = 8681080
257 + 8680823 = 8681080
269 + 8680811 = 8681080
311 + 8680769 = 8681080

Showing the first eight; more decompositions exist.
