Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513394, here are decompositions:

23 + 513371 = 513394
41 + 513353 = 513394
47 + 513347 = 513394
53 + 513341 = 513394
83 + 513311 = 513394
137 + 513257 = 513394
191 + 513203 = 513394
227 + 513167 = 513394

Showing the first eight; more decompositions exist.
