Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80910, here are decompositions:

13 + 80897 = 80910
47 + 80863 = 80910
61 + 80849 = 80910
79 + 80831 = 80910
101 + 80809 = 80910
107 + 80803 = 80910
127 + 80783 = 80910
131 + 80779 = 80910

Showing the first eight; more decompositions exist.
