Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691444, here are decompositions:

11 + 8691433 = 8691444
31 + 8691413 = 8691444
37 + 8691407 = 8691444
53 + 8691391 = 8691444
61 + 8691383 = 8691444
71 + 8691373 = 8691444
131 + 8691313 = 8691444
163 + 8691281 = 8691444

Showing the first eight; more decompositions exist.
