Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620258, here are decompositions:

41 + 8620217 = 8620258
47 + 8620211 = 8620258
71 + 8620187 = 8620258
107 + 8620151 = 8620258
137 + 8620121 = 8620258
149 + 8620109 = 8620258
389 + 8619869 = 8620258
401 + 8619857 = 8620258

Showing the first eight; more decompositions exist.
