Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20346, here are decompositions:

5 + 20341 = 20346
13 + 20333 = 20346
19 + 20327 = 20346
23 + 20323 = 20346
59 + 20287 = 20346
97 + 20249 = 20346
113 + 20233 = 20346
127 + 20219 = 20346

Showing the first eight; more decompositions exist.
