Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653442, here are decompositions:

163 + 8653279 = 8653442
181 + 8653261 = 8653442
199 + 8653243 = 8653442
211 + 8653231 = 8653442
223 + 8653219 = 8653442
271 + 8653171 = 8653442
331 + 8653111 = 8653442
349 + 8653093 = 8653442

Showing the first eight; more decompositions exist.
