Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691370, here are decompositions:

3 + 8691367 = 8691370
11 + 8691359 = 8691370
71 + 8691299 = 8691370
89 + 8691281 = 8691370
101 + 8691269 = 8691370
131 + 8691239 = 8691370
251 + 8691119 = 8691370
269 + 8691101 = 8691370

Showing the first eight; more decompositions exist.
