Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20888, here are decompositions:

31 + 20857 = 20888
79 + 20809 = 20888
139 + 20749 = 20888
157 + 20731 = 20888
181 + 20707 = 20888
277 + 20611 = 20888
337 + 20551 = 20888
367 + 20521 = 20888

Showing the first eight; more decompositions exist.
