Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81044, here are decompositions:

3 + 81041 = 81044
13 + 81031 = 81044
31 + 81013 = 81044
43 + 81001 = 81044
127 + 80917 = 81044
181 + 80863 = 81044
211 + 80833 = 81044
241 + 80803 = 81044

Showing the first eight; more decompositions exist.
