Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618898, here are decompositions:

5 + 8618893 = 8618898
19 + 8618879 = 8618898
31 + 8618867 = 8618898
37 + 8618861 = 8618898
47 + 8618851 = 8618898
89 + 8618809 = 8618898
109 + 8618789 = 8618898
139 + 8618759 = 8618898

Showing the first eight; more decompositions exist.
