Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20444, here are decompositions:

3 + 20441 = 20444
13 + 20431 = 20444
37 + 20407 = 20444
97 + 20347 = 20444
103 + 20341 = 20444
157 + 20287 = 20444
211 + 20233 = 20444
271 + 20173 = 20444

Showing the first eight; more decompositions exist.
