Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620464, here are decompositions:

71 + 8620393 = 8620464
103 + 8620361 = 8620464
137 + 8620327 = 8620464
157 + 8620307 = 8620464
197 + 8620267 = 8620464
233 + 8620231 = 8620464
277 + 8620187 = 8620464
313 + 8620151 = 8620464

Showing the first eight; more decompositions exist.
