Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691180, here are decompositions:

13 + 8691167 = 8691180
23 + 8691157 = 8691180
53 + 8691127 = 8691180
61 + 8691119 = 8691180
79 + 8691101 = 8691180
89 + 8691091 = 8691180
137 + 8691043 = 8691180
227 + 8690953 = 8691180

Showing the first eight; more decompositions exist.
