Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691474, here are decompositions:

5 + 8691469 = 8691474
23 + 8691451 = 8691474
41 + 8691433 = 8691474
61 + 8691413 = 8691474
67 + 8691407 = 8691474
83 + 8691391 = 8691474
101 + 8691373 = 8691474
107 + 8691367 = 8691474

Showing the first eight; more decompositions exist.
