Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80018, here are decompositions:

19 + 79999 = 80018
31 + 79987 = 80018
79 + 79939 = 80018
151 + 79867 = 80018
157 + 79861 = 80018
241 + 79777 = 80018
331 + 79687 = 80018
349 + 79669 = 80018

Showing the first eight; more decompositions exist.
