Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20370, here are decompositions:

11 + 20359 = 20370
13 + 20357 = 20370
17 + 20353 = 20370
23 + 20347 = 20370
29 + 20341 = 20370
37 + 20333 = 20370
43 + 20327 = 20370
47 + 20323 = 20370

Showing the first eight; more decompositions exist.
