Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81950, here are decompositions:

7 + 81943 = 81950
13 + 81937 = 81950
19 + 81931 = 81950
31 + 81919 = 81950
67 + 81883 = 81950
97 + 81853 = 81950
103 + 81847 = 81950
151 + 81799 = 81950

Showing the first eight; more decompositions exist.
