Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20534, here are decompositions:

13 + 20521 = 20534
103 + 20431 = 20534
127 + 20407 = 20534
181 + 20353 = 20534
193 + 20341 = 20534
211 + 20323 = 20534
373 + 20161 = 20534
421 + 20113 = 20534

Showing the first eight; more decompositions exist.
