Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81444, here are decompositions:

5 + 81439 = 81444
23 + 81421 = 81444
43 + 81401 = 81444
71 + 81373 = 81444
73 + 81371 = 81444
101 + 81343 = 81444
113 + 81331 = 81444
137 + 81307 = 81444

Showing the first eight; more decompositions exist.
