Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20546, here are decompositions:

3 + 20543 = 20546
13 + 20533 = 20546
37 + 20509 = 20546
67 + 20479 = 20546
103 + 20443 = 20546
139 + 20407 = 20546
157 + 20389 = 20546
193 + 20353 = 20546

Showing the first eight; more decompositions exist.
