Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81124, here are decompositions:

5 + 81119 = 81124
23 + 81101 = 81124
41 + 81083 = 81124
47 + 81077 = 81124
53 + 81071 = 81124
83 + 81041 = 81124
101 + 81023 = 81124
107 + 81017 = 81124

Showing the first eight; more decompositions exist.
