Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505984, here are decompositions:

5 + 505979 = 505984
23 + 505961 = 505984
107 + 505877 = 505984
113 + 505871 = 505984
173 + 505811 = 505984
257 + 505727 = 505984
293 + 505691 = 505984
383 + 505601 = 505984

Showing the first eight; more decompositions exist.
