Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691174, here are decompositions:

7 + 8691167 = 8691174
17 + 8691157 = 8691174
47 + 8691127 = 8691174
73 + 8691101 = 8691174
83 + 8691091 = 8691174
131 + 8691043 = 8691174
211 + 8690963 = 8691174
223 + 8690951 = 8691174

Showing the first eight; more decompositions exist.
