Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691268, here are decompositions:

17 + 8691251 = 8691268
29 + 8691239 = 8691268
59 + 8691209 = 8691268
101 + 8691167 = 8691268
149 + 8691119 = 8691268
167 + 8691101 = 8691268
317 + 8690951 = 8691268
347 + 8690921 = 8691268

Showing the first eight; more decompositions exist.
