Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63686, here are decompositions:

19 + 63667 = 63686
37 + 63649 = 63686
79 + 63607 = 63686
97 + 63589 = 63686
109 + 63577 = 63686
127 + 63559 = 63686
193 + 63493 = 63686
199 + 63487 = 63686

Showing the first eight; more decompositions exist.
