Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502878, here are decompositions:

17 + 502861 = 502878
31 + 502847 = 502878
37 + 502841 = 502878
59 + 502819 = 502878
71 + 502807 = 502878
97 + 502781 = 502878
107 + 502771 = 502878
109 + 502769 = 502878

Showing the first eight; more decompositions exist.
