Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80146, here are decompositions:

5 + 80141 = 80146
107 + 80039 = 80146
149 + 79997 = 80146
167 + 79979 = 80146
173 + 79973 = 80146
179 + 79967 = 80146
239 + 79907 = 80146
257 + 79889 = 80146

Showing the first eight; more decompositions exist.
