Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81304, here are decompositions:

5 + 81299 = 81304
11 + 81293 = 81304
23 + 81281 = 81304
71 + 81233 = 81304
101 + 81203 = 81304
107 + 81197 = 81304
131 + 81173 = 81304
173 + 81131 = 81304

Showing the first eight; more decompositions exist.
