Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20588, here are decompositions:

37 + 20551 = 20588
67 + 20521 = 20588
79 + 20509 = 20588
109 + 20479 = 20588
157 + 20431 = 20588
181 + 20407 = 20588
199 + 20389 = 20588
229 + 20359 = 20588

Showing the first eight; more decompositions exist.
