Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505434, here are decompositions:

5 + 505429 = 505434
23 + 505411 = 505434
67 + 505367 = 505434
107 + 505327 = 505434
113 + 505321 = 505434
151 + 505283 = 505434
157 + 505277 = 505434
197 + 505237 = 505434

Showing the first eight; more decompositions exist.
