Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618358, here are decompositions:

19 + 8618339 = 8618358
29 + 8618329 = 8618358
31 + 8618327 = 8618358
41 + 8618317 = 8618358
61 + 8618297 = 8618358
71 + 8618287 = 8618358
101 + 8618257 = 8618358
107 + 8618251 = 8618358

Showing the first eight; more decompositions exist.
