Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3686, here are decompositions:

13 + 3673 = 3686
43 + 3643 = 3686
73 + 3613 = 3686
79 + 3607 = 3686
103 + 3583 = 3686
127 + 3559 = 3686
139 + 3547 = 3686
157 + 3529 = 3686

Showing the first eight; more decompositions exist.
