Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20264, here are decompositions:

3 + 20261 = 20264
31 + 20233 = 20264
103 + 20161 = 20264
151 + 20113 = 20264
157 + 20107 = 20264
163 + 20101 = 20264
193 + 20071 = 20264
241 + 20023 = 20264

Showing the first eight; more decompositions exist.
