Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20318, here are decompositions:

31 + 20287 = 20318
157 + 20161 = 20318
211 + 20107 = 20318
229 + 20089 = 20318
271 + 20047 = 20318
307 + 20011 = 20318
457 + 19861 = 20318
499 + 19819 = 20318

Showing the first eight; more decompositions exist.
