Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81944, here are decompositions:

7 + 81937 = 81944
13 + 81931 = 81944
43 + 81901 = 81944
61 + 81883 = 81944
97 + 81847 = 81944
127 + 81817 = 81944
241 + 81703 = 81944
277 + 81667 = 81944

Showing the first eight; more decompositions exist.
