Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19636, here are decompositions:

53 + 19583 = 19636
59 + 19577 = 19636
83 + 19553 = 19636
167 + 19469 = 19636
173 + 19463 = 19636
179 + 19457 = 19636
233 + 19403 = 19636
257 + 19379 = 19636

Showing the first eight; more decompositions exist.
