Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691258, here are decompositions:

7 + 8691251 = 8691258
11 + 8691247 = 8691258
19 + 8691239 = 8691258
29 + 8691229 = 8691258
47 + 8691211 = 8691258
71 + 8691187 = 8691258
101 + 8691157 = 8691258
131 + 8691127 = 8691258

Showing the first eight; more decompositions exist.
