Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81416, here are decompositions:

7 + 81409 = 81416
43 + 81373 = 81416
67 + 81349 = 81416
73 + 81343 = 81416
109 + 81307 = 81416
193 + 81223 = 81416
367 + 81049 = 81416
373 + 81043 = 81416

Showing the first eight; more decompositions exist.
