Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20612, here are decompositions:

13 + 20599 = 20612
19 + 20593 = 20612
61 + 20551 = 20612
79 + 20533 = 20612
103 + 20509 = 20612
181 + 20431 = 20612
223 + 20389 = 20612
271 + 20341 = 20612

Showing the first eight; more decompositions exist.
