Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691570, here are decompositions:

29 + 8691541 = 8691570
61 + 8691509 = 8691570
73 + 8691497 = 8691570
89 + 8691481 = 8691570
101 + 8691469 = 8691570
137 + 8691433 = 8691570
157 + 8691413 = 8691570
163 + 8691407 = 8691570

Showing the first eight; more decompositions exist.
