Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691566, here are decompositions:

97 + 8691469 = 8691566
193 + 8691373 = 8691566
199 + 8691367 = 8691566
337 + 8691229 = 8691566
379 + 8691187 = 8691566
409 + 8691157 = 8691566
439 + 8691127 = 8691566
523 + 8691043 = 8691566

Showing the first eight; more decompositions exist.
