Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103636, here are decompositions:

17 + 103619 = 103636
23 + 103613 = 103636
53 + 103583 = 103636
59 + 103577 = 103636
83 + 103553 = 103636
107 + 103529 = 103636
179 + 103457 = 103636
227 + 103409 = 103636

Showing the first eight; more decompositions exist.
