Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502872, here are decompositions:

11 + 502861 = 502872
31 + 502841 = 502872
43 + 502829 = 502872
53 + 502819 = 502872
101 + 502771 = 502872
103 + 502769 = 502872
173 + 502699 = 502872
229 + 502643 = 502872

Showing the first eight; more decompositions exist.
