Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691644, here are decompositions:

61 + 8691583 = 8691644
103 + 8691541 = 8691644
163 + 8691481 = 8691644
193 + 8691451 = 8691644
211 + 8691433 = 8691644
271 + 8691373 = 8691644
277 + 8691367 = 8691644
331 + 8691313 = 8691644

Showing the first eight; more decompositions exist.
