Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613906, here are decompositions:

13 + 8613893 = 8613906
19 + 8613887 = 8613906
43 + 8613863 = 8613906
53 + 8613853 = 8613906
79 + 8613827 = 8613906
89 + 8613817 = 8613906
97 + 8613809 = 8613906
109 + 8613797 = 8613906

Showing the first eight; more decompositions exist.
