Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618958, here are decompositions:

41 + 8618917 = 8618958
79 + 8618879 = 8618958
97 + 8618861 = 8618958
107 + 8618851 = 8618958
149 + 8618809 = 8618958
199 + 8618759 = 8618958
211 + 8618747 = 8618958
269 + 8618689 = 8618958

Showing the first eight; more decompositions exist.
