Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618406, here are decompositions:

19 + 8618387 = 8618406
29 + 8618377 = 8618406
67 + 8618339 = 8618406
79 + 8618327 = 8618406
89 + 8618317 = 8618406
109 + 8618297 = 8618406
113 + 8618293 = 8618406
149 + 8618257 = 8618406

Showing the first eight; more decompositions exist.
