Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80250, here are decompositions:

11 + 80239 = 80250
17 + 80233 = 80250
19 + 80231 = 80250
29 + 80221 = 80250
41 + 80209 = 80250
43 + 80207 = 80250
59 + 80191 = 80250
73 + 80177 = 80250

Showing the first eight; more decompositions exist.
