Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691256, here are decompositions:

5 + 8691251 = 8691256
17 + 8691239 = 8691256
47 + 8691209 = 8691256
89 + 8691167 = 8691256
137 + 8691119 = 8691256
293 + 8690963 = 8691256
389 + 8690867 = 8691256
443 + 8690813 = 8691256

Showing the first eight; more decompositions exist.
