Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681522, here are decompositions:

19 + 8681503 = 8681522
163 + 8681359 = 8681522
181 + 8681341 = 8681522
211 + 8681311 = 8681522
271 + 8681251 = 8681522
331 + 8681191 = 8681522
433 + 8681089 = 8681522
463 + 8681059 = 8681522

Showing the first eight; more decompositions exist.
