Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80856, here are decompositions:

7 + 80849 = 80856
23 + 80833 = 80856
37 + 80819 = 80856
47 + 80809 = 80856
53 + 80803 = 80856
67 + 80789 = 80856
73 + 80783 = 80856
79 + 80777 = 80856

Showing the first eight; more decompositions exist.
