Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691170, here are decompositions:

3 + 8691167 = 8691170
13 + 8691157 = 8691170
43 + 8691127 = 8691170
79 + 8691091 = 8691170
127 + 8691043 = 8691170
151 + 8691019 = 8691170
199 + 8690971 = 8691170
211 + 8690959 = 8691170

Showing the first eight; more decompositions exist.
