Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620408, here are decompositions:

47 + 8620361 = 8620408
59 + 8620349 = 8620408
101 + 8620307 = 8620408
131 + 8620277 = 8620408
149 + 8620259 = 8620408
191 + 8620217 = 8620408
197 + 8620211 = 8620408
257 + 8620151 = 8620408

Showing the first eight; more decompositions exist.
