Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691836, here are decompositions:

3 + 8691833 = 8691836
37 + 8691799 = 8691836
73 + 8691763 = 8691836
103 + 8691733 = 8691836
163 + 8691673 = 8691836
193 + 8691643 = 8691836
367 + 8691469 = 8691836
463 + 8691373 = 8691836

Showing the first eight; more decompositions exist.
