Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691446, here are decompositions:

13 + 8691433 = 8691446
73 + 8691373 = 8691446
79 + 8691367 = 8691446
199 + 8691247 = 8691446
223 + 8691223 = 8691446
487 + 8690959 = 8691446
499 + 8690947 = 8691446
619 + 8690827 = 8691446

Showing the first eight; more decompositions exist.
