Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691470, here are decompositions:

19 + 8691451 = 8691470
37 + 8691433 = 8691470
79 + 8691391 = 8691470
97 + 8691373 = 8691470
103 + 8691367 = 8691470
157 + 8691313 = 8691470
223 + 8691247 = 8691470
241 + 8691229 = 8691470

Showing the first eight; more decompositions exist.
