Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168394, here are decompositions:

3 + 168391 = 168394
41 + 168353 = 168394
47 + 168347 = 168394
71 + 168323 = 168394
101 + 168293 = 168394
113 + 168281 = 168394
131 + 168263 = 168394
167 + 168227 = 168394

Showing the first eight; more decompositions exist.
