Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506388, here are decompositions:

7 + 506381 = 506388
31 + 506357 = 506388
37 + 506351 = 506388
41 + 506347 = 506388
59 + 506329 = 506388
61 + 506327 = 506388
97 + 506291 = 506388
107 + 506281 = 506388

Showing the first eight; more decompositions exist.
