Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620240, here are decompositions:

23 + 8620217 = 8620240
29 + 8620211 = 8620240
53 + 8620187 = 8620240
89 + 8620151 = 8620240
107 + 8620133 = 8620240
131 + 8620109 = 8620240
191 + 8620049 = 8620240
197 + 8620043 = 8620240

Showing the first eight; more decompositions exist.
