Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691494, here are decompositions:

13 + 8691481 = 8691494
43 + 8691451 = 8691494
61 + 8691433 = 8691494
103 + 8691391 = 8691494
127 + 8691367 = 8691494
181 + 8691313 = 8691494
271 + 8691223 = 8691494
283 + 8691211 = 8691494

Showing the first eight; more decompositions exist.
