Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80406, here are decompositions:

19 + 80387 = 80406
37 + 80369 = 80406
43 + 80363 = 80406
59 + 80347 = 80406
89 + 80317 = 80406
97 + 80309 = 80406
127 + 80279 = 80406
167 + 80239 = 80406

Showing the first eight; more decompositions exist.
