Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755818, here are decompositions:

7 + 8755811 = 8755818
37 + 8755781 = 8755818
89 + 8755729 = 8755818
107 + 8755711 = 8755818
151 + 8755667 = 8755818
179 + 8755639 = 8755818
199 + 8755619 = 8755818
317 + 8755501 = 8755818

Showing the first eight; more decompositions exist.
