Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691450, here are decompositions:

17 + 8691433 = 8691450
37 + 8691413 = 8691450
43 + 8691407 = 8691450
59 + 8691391 = 8691450
67 + 8691383 = 8691450
83 + 8691367 = 8691450
137 + 8691313 = 8691450
151 + 8691299 = 8691450

Showing the first eight; more decompositions exist.
