Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620318, here are decompositions:

11 + 8620307 = 8620318
29 + 8620289 = 8620318
41 + 8620277 = 8620318
59 + 8620259 = 8620318
101 + 8620217 = 8620318
107 + 8620211 = 8620318
131 + 8620187 = 8620318
167 + 8620151 = 8620318

Showing the first eight; more decompositions exist.
