Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681822, here are decompositions:

43 + 8681779 = 8681822
199 + 8681623 = 8681822
283 + 8681539 = 8681822
349 + 8681473 = 8681822
421 + 8681401 = 8681822
463 + 8681359 = 8681822
571 + 8681251 = 8681822
601 + 8681221 = 8681822

Showing the first eight; more decompositions exist.
