Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20238, here are decompositions:

5 + 20233 = 20238
7 + 20231 = 20238
19 + 20219 = 20238
37 + 20201 = 20238
61 + 20177 = 20238
89 + 20149 = 20238
109 + 20129 = 20238
131 + 20107 = 20238

Showing the first eight; more decompositions exist.
