Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681122, here are decompositions:

5 + 8681117 = 8681122
11 + 8681111 = 8681122
101 + 8681021 = 8681122
113 + 8681009 = 8681122
251 + 8680871 = 8681122
311 + 8680811 = 8681122
353 + 8680769 = 8681122
389 + 8680733 = 8681122

Showing the first eight; more decompositions exist.
