Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80810, here are decompositions:

7 + 80803 = 80810
31 + 80779 = 80810
61 + 80749 = 80810
73 + 80737 = 80810
97 + 80713 = 80810
109 + 80701 = 80810
127 + 80683 = 80810
139 + 80671 = 80810

Showing the first eight; more decompositions exist.
