Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654220, here are decompositions:

19 + 8654201 = 8654220
37 + 8654183 = 8654220
73 + 8654147 = 8654220
97 + 8654123 = 8654220
103 + 8654117 = 8654220
109 + 8654111 = 8654220
131 + 8654089 = 8654220
163 + 8654057 = 8654220

Showing the first eight; more decompositions exist.
