Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681042, here are decompositions:

103 + 8680939 = 8681042
229 + 8680813 = 8681042
241 + 8680801 = 8681042
373 + 8680669 = 8681042
499 + 8680543 = 8681042
541 + 8680501 = 8681042
571 + 8680471 = 8681042
673 + 8680369 = 8681042

Showing the first eight; more decompositions exist.
