Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80366, here are decompositions:

3 + 80363 = 80366
19 + 80347 = 80366
37 + 80329 = 80366
79 + 80287 = 80366
103 + 80263 = 80366
127 + 80239 = 80366
157 + 80209 = 80366
193 + 80173 = 80366

Showing the first eight; more decompositions exist.
