Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761818, here are decompositions:

11 + 8761807 = 8761818
29 + 8761789 = 8761818
67 + 8761751 = 8761818
97 + 8761721 = 8761818
127 + 8761691 = 8761818
179 + 8761639 = 8761818
199 + 8761619 = 8761818
271 + 8761547 = 8761818

Showing the first eight; more decompositions exist.
