Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645190, here are decompositions:

11 + 8645179 = 8645190
67 + 8645123 = 8645190
109 + 8645081 = 8645190
137 + 8645053 = 8645190
167 + 8645023 = 8645190
179 + 8645011 = 8645190
181 + 8645009 = 8645190
199 + 8644991 = 8645190

Showing the first eight; more decompositions exist.
