Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618270, here are decompositions:

13 + 8618257 = 8618270
19 + 8618251 = 8618270
97 + 8618173 = 8618270
139 + 8618131 = 8618270
151 + 8618119 = 8618270
163 + 8618107 = 8618270
181 + 8618089 = 8618270
211 + 8618059 = 8618270

Showing the first eight; more decompositions exist.
