Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108636, here are decompositions:

5 + 108631 = 108636
79 + 108557 = 108636
83 + 108553 = 108636
103 + 108533 = 108636
107 + 108529 = 108636
137 + 108499 = 108636
139 + 108497 = 108636
173 + 108463 = 108636

Showing the first eight; more decompositions exist.
