Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20282, here are decompositions:

13 + 20269 = 20282
109 + 20173 = 20282
139 + 20143 = 20282
181 + 20101 = 20282
193 + 20089 = 20282
211 + 20071 = 20282
271 + 20011 = 20282
421 + 19861 = 20282

Showing the first eight; more decompositions exist.
