Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20508, here are decompositions:

29 + 20479 = 20508
31 + 20477 = 20508
67 + 20441 = 20508
97 + 20411 = 20508
101 + 20407 = 20508
109 + 20399 = 20508
139 + 20369 = 20508
149 + 20359 = 20508

Showing the first eight; more decompositions exist.
