Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644308, here are decompositions:

7 + 8644301 = 8644308
47 + 8644261 = 8644308
137 + 8644171 = 8644308
151 + 8644157 = 8644308
227 + 8644081 = 8644308
251 + 8644057 = 8644308
311 + 8643997 = 8644308
317 + 8643991 = 8644308

Showing the first eight; more decompositions exist.
