Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81026, here are decompositions:

3 + 81023 = 81026
7 + 81019 = 81026
13 + 81013 = 81026
37 + 80989 = 81026
73 + 80953 = 81026
97 + 80929 = 81026
103 + 80923 = 81026
109 + 80917 = 81026

Showing the first eight; more decompositions exist.
