Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80394, here are decompositions:

7 + 80387 = 80394
31 + 80363 = 80394
47 + 80347 = 80394
53 + 80341 = 80394
107 + 80287 = 80394
131 + 80263 = 80394
163 + 80231 = 80394
173 + 80221 = 80394

Showing the first eight; more decompositions exist.
