Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81446, here are decompositions:

7 + 81439 = 81446
37 + 81409 = 81446
73 + 81373 = 81446
97 + 81349 = 81446
103 + 81343 = 81446
139 + 81307 = 81446
163 + 81283 = 81446
223 + 81223 = 81446

Showing the first eight; more decompositions exist.
