Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505992, here are decompositions:

13 + 505979 = 505992
23 + 505969 = 505992
31 + 505961 = 505992
43 + 505949 = 505992
73 + 505919 = 505992
173 + 505819 = 505992
181 + 505811 = 505992
211 + 505781 = 505992

Showing the first eight; more decompositions exist.
