Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501972, here are decompositions:

5 + 501967 = 501972
19 + 501953 = 501972
41 + 501931 = 501972
61 + 501911 = 501972
83 + 501889 = 501972
109 + 501863 = 501972
131 + 501841 = 501972
151 + 501821 = 501972

Showing the first eight; more decompositions exist.
