Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620308, here are decompositions:

19 + 8620289 = 8620308
31 + 8620277 = 8620308
41 + 8620267 = 8620308
89 + 8620219 = 8620308
97 + 8620211 = 8620308
149 + 8620159 = 8620308
157 + 8620151 = 8620308
167 + 8620141 = 8620308

Showing the first eight; more decompositions exist.
