Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691226, here are decompositions:

3 + 8691223 = 8691226
17 + 8691209 = 8691226
59 + 8691167 = 8691226
107 + 8691119 = 8691226
263 + 8690963 = 8691226
359 + 8690867 = 8691226
443 + 8690783 = 8691226
563 + 8690663 = 8691226

Showing the first eight; more decompositions exist.
