Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505398, here are decompositions:

29 + 505369 = 505398
31 + 505367 = 505398
41 + 505357 = 505398
59 + 505339 = 505398
71 + 505327 = 505398
79 + 505319 = 505398
97 + 505301 = 505398
167 + 505231 = 505398

Showing the first eight; more decompositions exist.
