Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80538, here are decompositions:

11 + 80527 = 80538
47 + 80491 = 80538
67 + 80471 = 80538
89 + 80449 = 80538
109 + 80429 = 80538
131 + 80407 = 80538
151 + 80387 = 80538
191 + 80347 = 80538

Showing the first eight; more decompositions exist.
