Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80450, here are decompositions:

3 + 80447 = 80450
43 + 80407 = 80450
103 + 80347 = 80450
109 + 80341 = 80450
163 + 80287 = 80450
199 + 80251 = 80450
211 + 80239 = 80450
229 + 80221 = 80450

Showing the first eight; more decompositions exist.
