Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645204, here are decompositions:

151 + 8645053 = 8645204
157 + 8645047 = 8645204
181 + 8645023 = 8645204
193 + 8645011 = 8645204
241 + 8644963 = 8645204
277 + 8644927 = 8645204
331 + 8644873 = 8645204
433 + 8644771 = 8645204

Showing the first eight; more decompositions exist.
