Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691456, here are decompositions:

5 + 8691451 = 8691456
23 + 8691433 = 8691456
43 + 8691413 = 8691456
73 + 8691383 = 8691456
83 + 8691373 = 8691456
89 + 8691367 = 8691456
97 + 8691359 = 8691456
157 + 8691299 = 8691456

Showing the first eight; more decompositions exist.
