Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20474, here are decompositions:

31 + 20443 = 20474
43 + 20431 = 20474
67 + 20407 = 20474
127 + 20347 = 20474
151 + 20323 = 20474
241 + 20233 = 20474
313 + 20161 = 20474
331 + 20143 = 20474

Showing the first eight; more decompositions exist.
