Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20364, here are decompositions:

5 + 20359 = 20364
7 + 20357 = 20364
11 + 20353 = 20364
17 + 20347 = 20364
23 + 20341 = 20364
31 + 20333 = 20364
37 + 20327 = 20364
41 + 20323 = 20364

Showing the first eight; more decompositions exist.
