Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618288, here are decompositions:

31 + 8618257 = 8618288
37 + 8618251 = 8618288
67 + 8618221 = 8618288
139 + 8618149 = 8618288
157 + 8618131 = 8618288
181 + 8618107 = 8618288
199 + 8618089 = 8618288
229 + 8618059 = 8618288

Showing the first eight; more decompositions exist.
