Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681222, here are decompositions:

31 + 8681191 = 8681222
163 + 8681059 = 8681222
229 + 8680993 = 8681222
271 + 8680951 = 8681222
283 + 8680939 = 8681222
313 + 8680909 = 8681222
409 + 8680813 = 8681222
421 + 8680801 = 8681222

Showing the first eight; more decompositions exist.
