Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81554, here are decompositions:

3 + 81551 = 81554
7 + 81547 = 81554
37 + 81517 = 81554
97 + 81457 = 81554
181 + 81373 = 81554
211 + 81343 = 81554
223 + 81331 = 81554
271 + 81283 = 81554

Showing the first eight; more decompositions exist.
