Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81054, here are decompositions:

5 + 81049 = 81054
7 + 81047 = 81054
11 + 81043 = 81054
13 + 81041 = 81054
23 + 81031 = 81054
31 + 81023 = 81054
37 + 81017 = 81054
41 + 81013 = 81054

Showing the first eight; more decompositions exist.
