Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20600, here are decompositions:

7 + 20593 = 20600
37 + 20563 = 20600
67 + 20533 = 20600
79 + 20521 = 20600
157 + 20443 = 20600
193 + 20407 = 20600
211 + 20389 = 20600
241 + 20359 = 20600

Showing the first eight; more decompositions exist.
