Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691468, here are decompositions:

17 + 8691451 = 8691468
61 + 8691407 = 8691468
101 + 8691367 = 8691468
109 + 8691359 = 8691468
199 + 8691269 = 8691468
229 + 8691239 = 8691468
239 + 8691229 = 8691468
257 + 8691211 = 8691468

Showing the first eight; more decompositions exist.
