Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690636, here are decompositions:

37 + 8690599 = 8690636
43 + 8690593 = 8690636
79 + 8690557 = 8690636
223 + 8690413 = 8690636
277 + 8690359 = 8690636
433 + 8690203 = 8690636
463 + 8690173 = 8690636
547 + 8690089 = 8690636

Showing the first eight; more decompositions exist.
