Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81234, here are decompositions:

11 + 81223 = 81234
31 + 81203 = 81234
37 + 81197 = 81234
53 + 81181 = 81234
61 + 81173 = 81234
71 + 81163 = 81234
103 + 81131 = 81234
137 + 81097 = 81234

Showing the first eight; more decompositions exist.
