Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501984, here are decompositions:

13 + 501971 = 501984
17 + 501967 = 501984
31 + 501953 = 501984
37 + 501947 = 501984
53 + 501931 = 501984
73 + 501911 = 501984
157 + 501827 = 501984
163 + 501821 = 501984

Showing the first eight; more decompositions exist.
