Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81050, here are decompositions:

3 + 81047 = 81050
7 + 81043 = 81050
19 + 81031 = 81050
31 + 81019 = 81050
37 + 81013 = 81050
61 + 80989 = 81050
97 + 80953 = 81050
127 + 80923 = 81050

Showing the first eight; more decompositions exist.
