Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681026, here are decompositions:

5 + 8681021 = 8681026
17 + 8681009 = 8681026
23 + 8681003 = 8681026
257 + 8680769 = 8681026
293 + 8680733 = 8681026
443 + 8680583 = 8681026
467 + 8680559 = 8681026
587 + 8680439 = 8681026

Showing the first eight; more decompositions exist.
